Shift+ some keys missed in jumanji, dwm on Sony Vaio F12

I have a strange issue on my Sony Vaio F12. Shift + some keys seem to become <some keys> only. For example Shift+space in jumanji is interpreted as Space only. Shift+Mod4+Ctrl+Q in dwm isn't caught properly, while Shift+Mod4+Enter is. xev seem to get it right, though. The state is 0x0 when pressing Space only, and 0x1 at Shift+Space.
(Note: I'm currently moving to a fresh Arch install (x86_64) on a new computer. These key combinations, including the dwm one, worked fine on my old 32bit install on a Dell XPS m1330, so the configs should be right).
Any ideas?
Thanks in advance,
halhen

Thanks for the suggestion about customizing function keys, however, since the keys currently do nothing there's nothing to be re-mapped. (Such as VolumeUp => Page Up.)
As far as I can tell, use of the Fn key actually blocks the arrow key press events on the Yoga, so not even Up, Down. Left, Right presses are received by the OS if/when the function key is pressed. (This be can verified in any basic text editing program such as Notepad. Additionally, I wrote a program to display any/all received key events and confirmed no event occurs in such cases.)
The keyboard firmware or driver must be receiving the key state changes but simply ignores any arrow key event if the function key is pressed. I suspect any change to this behavior would have to come from the firmware or driver, which currently intercepts the hardware button presses before the OS may have a chance to redirect them. So I think the Lenovo hardware/software guys would have to enable this, which I figured it wouldn't hurt to ask.
I like the use of the function key in conjunction with the arrows because that way I don't need to move my fingers off the arrow keys in order to move the text cursor to the beginning or end of a line. (I certainly still find the fixed Home and End keys on the keyboard necessary.)
(Oh, and I apologize for inserting an image >50k, I didn't know the forum rules concerning a maximum image size.)

Wireless keyboard right shift don't work with some keys but left shift works

So, this is really a strange behaviour under Mavericks 10.9.5
My right shift doesn't like some "keys" and some keys don't like the shifts ( either left or right ). For example:
doing a " ? " or a " B " or a " % " with the right shift doesn't work. I mean, after i remove the batteries and stay without using the keyboard for a day or two, when i get back to it, it works for a couple of minutes. But after that... i just can do a capital B or a ? with the right ****. Although i can do all other characters.
the " t " key is another one. No caps here, with either left or right shift key. But the key by itself is working just fine.
So i'm not really 100% convinced it's an hardware fault, because the all keys are working properly in other situations.
Any idea about this strange behaviour?
thank you for your time,
Regards
Pedro.

Hello Postmodum,
Check out the article below and turn on the keyboard viewer to see what happens to the keyboard when you press the right shift key. You may find out that it may be linked to add another combination of keys, which can produce the odd behavior that you are describing.

Macbook misses some key events for a few seconds

I have noticed that for last two months or so something strange happens to my Retina MBP. Once in a couple of days it stops responding to some key events. It is like it handles only one keypress out of 4-5. Nothing seems to be wrong with the keyboard and it is not about a particular key or keys. And about 10-15 seconds later everything goes back to normal. I do not see any suspicious messages in the logs, the computer is connected to the power supply...It happens just by itself in the middle of the day, when I am typing.
Almost looks like some interrupts get lost by the system while it is busy with something else. But I have checked the load level and running processes - nothing interesting there....And whatever it is - it happens during a very short period of time.

Hi,
No, I have not returned my MBP yet. In fact, I would rather avoid doing this unless I am convinced if it is a hardware issue. And I do believe it is not. Just recently I have spent some time investigating it and I have found very stroing correlation between the moments when this happens and these messages in the kernel log:
Jan 13 10:49:54 mbp-wifi kernel[0]: Sandbox: sandboxd(96471) deny mach-lookup com.apple.coresymbolicationd
Jan 13 10:54:31 mbp-wifi kernel[0]: Sandbox: sandboxd(96499) deny mach-lookup com.apple.coresymbolicationd
Jan 13 10:54:31 mbp-wifi.home sandboxd[96499] ([96497]): mdworker(96497) deny mach-lookup com.apple.ls.boxd
Jan 13 10:54:31 mbp-wifi.home sandboxd[96499] ([96498]): mdworker(96498) deny mach-lookup com.apple.ls.boxd
Jan 13 10:56:32 mbp-wifi.home sandboxd[96504] ([96503]): mdworker(96503) deny mach-lookup com.apple.ls.boxd
Jan 13 10:56:32 mbp-wifi.home sandboxd[96504] ([96502]): mdworker(96502) deny mach-lookup com.apple.ls.boxd
And I have also noticed that my Spotlight database gets reconstructed too often, which means it gets corrupted.
From all this I conclude that it is most likely the software issue and it seems to be linked to spotlight. I saw people reporting similar things. So now I am researching on how to fix it without disabling the spotlight.
In general, I believe that the quality of Apple software is going down, it is not like 4-5 years ago And Apple does seem to care less and less about it.
If in your case it happens all the time, not just once in a while, and you see that a particular key has problems - it is possible that we are talking about the different issues and yours might be really about the keyboard.

Some Keys are not working on Lenovo G570

Hello all
I am new here, looking for some help regarding my Lenovo G570.
Yesterday, it was working perfectly, I properly shut is down. I have set a BIOS pasword.
Today, when I switch it on, I was unable to type the pasword becasu some keys were not working. However, I managed to loged in with the help of On Screen Keyboard. After analysing it, I came to know that some keys on numpad includeing 0,2 and on the 2nd line(vertical numerical keys) 1,2,3,4,7,8,9,0 are not working. I tried to re-install the OS but I set a BIOS paswoed containing one of the missing keys.
Please let me know whether it is a software problem or should i take my laptop to some repairing shop?
Thanks
Solved!

Laptop Keyboard problem, some keys get randomly ignored

Hello,
This is a problem that occurs with all razer blade notebooks when running linux (does not occur in Windows 8); some keys get randomly ignored when you type at your normal speed, and it is very frustating especially when typing passwords or programming. At the moment we have to type very slowly in order to get all keystrokes caught. The keyboard has antighosting technology, maybe that info is useful.
This is the further we went in this post:
https://bbs.archlinux.org/viewtopic.php?id=161634
In that post, a forum partner proposed to modify "drivers/hid/usbhid/hid-core.c" and set "interval = 1;" right after the mouse pooling interval was set, around line 1134 of the file. When we use that modified kernel, the keyboard feels a little better but i still get ignored keys when typing at normal speed.

Does anyone know, based on their experience, what could be the cause of the keyboard malfunction?
Does this type of error occur for some other notebooks too?
It would be great if someone could point me in the right direction for where to look.

For all i know (Not a lot) I'm thinking it might have something to do with your usb?(Worst answer ever!)
Did you try a different port.
Please let me know if this worked .
On the side(What kernel version are you running?)
Hi. Well in this case the problem is with the Razer Blade Laptop's keyboard, therefore i cannot choose another port. You gave me an idea however, i will try to get any usb keyboard, plug it into the razer blade and make sure it works so that i can discard any major problem.

I accidently knocked some keys on the keyboard and firfox is now lost at the top of the screen, I cannot see menu items if I push the curser up some of the top appears on my screen but not all please can you help me?

I accidently knocked some keys on my keyboard. I do not know which keys my hand knocked but it caused Firefox to go beyond my visible screen at the top. The base of Firefox is still okay and views correctly. But the head is missing I cannot access my menus items such as Bookmarks etc. The screen does drop down if I push my curser up but not enough to show the menu items. Can you please help?

Thank you for your help - this definitely sorted it out!

CS5 illustrator 'shift arrow'/cmd shift arrow' keys wont work! (Help!)

Hi,
I have just installed the CS5 web suite and are loving it so far, however for some strange reason when I try to move an object or point by holding down the shift - arrrow or cmd shift arrow key, (as you do) nothing happens!
Have tried restarting etc but to no avail... Works fine in Photoshop and other apps, but no go in ai... Any suggestions please as it's really annoying!
(Never come across this before in previous versions..)
Thanks,
Dean

It actually seem to have worked for you as well as you cannot copy and paste the settings folder from one version to another since the prefernces are tied to a different folder so if you moved or trashed the folder or replaced it in some way like changing the name of CS 4 to CS 5 then all you did is the same as above since Illustrator just created a new set of preferences and settings anyway.
So the above actually worked for you once you quit and restarted Illustrator.
Here look from my preferences folder CS 4 and CS 5 living confidentially side by side.
BTW if you just removed the preference file within this folder you did not follow the instructions correctly you have to get rid of the whole settings folder.

I have a mac book pro but I'm sing some keys from the keyboard

How can't I get my Keyboard replace?

Hi. Are you saying that you are missing some keys on the MBP? If the keys are missing, but the keyboard works ,then all you need is the missing keys. If you know what keys are missing you can buy them on Ebay and replace them Look at or look up keyboard for your MBP and write down what keys you need. Here is a link that shows how this is done. http://www.insidemylaptop.com/how-to-repair-damaged-key-on-macbook-pro-keyboard/ This most likely cheaper than replacing the entire keyboard.

IBook G4 "K" Keyboard Key dosen't work without using the "Shift" keyboard key.

Some reason, now my iBook G4's "K" keyboard key won't work inless if i use the "Shift" keyboard key.
Help!

When you press it, what speaks and what does it say?
Mine does not do that. Not on my portables nor desktop
Macs. So I wonder what else may be happening.
When did your iBook start doing this? Are there any
other applications open that may have a keyboard
shortcut? The System Preferences> keyboard> may
show a few things that can be set, options. Also see
if there isn't something set in Universal Access. A few
of the preference settings in universal access can be
engaged by just a few keys, and can be shut off there.
{Check into Voice Over Utility, as there is a pile of stuff
in there, which could allow sounds when keyboarding
and capitals can activate. Only if it's been set.}
And the Speech system preference panel can allow
a key to be set for several functions. Mine do not
have any assigned, and by default none should be.
Good luck & happy computing!

Some keys on keyboard don't work

I got a used MacBook air on eBay and I noticed the some keys on the keyboard don't work as intended.
For example, the '1' key does not work at all, the 'p' key would increase the volume, the 'delete' key would enable capslock.
I've tried to do a clean install of Mac OS X but it would still do the same thing.
Is my logic board broken?
What else can I try to make sure that the keyboard is the problem and not the software?

Hello:
Try resetting the PRAM.
By the way, what tests are you referring to?

I have an ancient laptop (from 2005) that has my entire music library. This laptop barely works and some keys don't type anymore. How can I get all this music transferred to another computer, or available to me on the cloud?

No... do not move programs.
About the iTunes library files
Your iTunes library files track the media you add to iTunes, how you've organized it, and other information such as playlists. By default, these two files are in your iTunes folder:

Some keys on keyboard not working.

Hello,
I´ve pushed lots of buttons at the same time on accident. and now for some reason, some keys are not responding. I´m pretty sure it´s not broken cause i didn´t push it hard, just a normal push.
? button is not working
: button is not working
1, 3, 4, 6, 7 and 9 keys on the right side of the keyboard are not working. (258 working fine)
it´s pretty strange because when i pushed a lot of buttons it weren´t those buttons on the right side of the keyboard. i didn´t even touch them.
So i think i did an keycombination on accident or something. It also has nothing to do with the language of the keyboard cause that´s all fine.
I´ve tried the keyboard on my macbook, mac pro and even a windows pc. it does the same thing on all 3 computers.
It´s an apple wired usb keyboard.
Does anyone know a solution?

i don't think it's damaged, i just pushed a few buttons at the same time, i don't think that can give damage to your keyboard. its not like i slammed it. i just pushed it slightly, if that means it can be damaged then it already would be broken because i type on it every day.
I can understand your frustration. But there is no way any key combo you might have done would affect more than one computer. I suggest you take it to an Apple store or other shop for them to test.

Some keys stopped responding apparently after latest update

Dear all,
all of the sudden, apparently after the latest update, some keys on my native keyboard stop responding from time to time. Mostly I can verify the problem with the a, s, k and l keys. It seems that pressing the combination ctrl+alt solves the problem for some time.
What I tried was
- checking the Activity Monitor for processes that take a large amount of CPU -> no.
- performing a P-RAM reset -> problem disappeared for an hour or so.
- safe mode, restore permissions -> did not have any affect at all.
It also seem that the external keyboard works without any problem (bluetooth).
Any hint or solution?

It's possible your macbook keyboard needs cleaning out. If you eat while using your computer, crumbs could have gotten underneath the keys. You should visit the macbook forums for instructions on keyboard cleaning in case that is the cause of your problems.

I hit some key or tab by accident and now my bookmarks are no longer in a list but viewable across a set of pages that I can scan left to right. I would like to go back to the other display which is much easier for me. Thanks for the help.

I hit some key or tab by accident and now my bookmarks are no longer in a list but in a page format that can be scanned left to right. I'd like to return to the listing format. How do I do this? Thanks!

Some keys are not working on my Satellite C notebook

since today i have some problems with some keys on my keyboard my Z, \ (left side next to the Z) and my FN key doesnt work (XD i had to copy and paste the Z) but this problem is realy anoying is there a way to fix this?

It is not known to me that single keys repair can be done.
In such case the whole keyboard must be replaced.
I dont know which notebook model and how old it is but it is possible that certain keys are broken.
What you can try is to remove key cap and check if key is dirty and see if there is some contact problem.
