The L and O keys on my keyboard stopped responding. Now locked out

After the L and O keys ceased responding I decided to restart my computer.
The computer is password protected and one of the elements to my password contains one of those letters.
So I am currently locked out of my computer as the key to enter the password is not responding.
Any help to at least get back in
And any further help in the keys?
I'm many miles away from any store
Thank You

single user mode
1) command + S
2) fsck -fy
3) mount uw /
4) passwd username [username=your username]
You will be prompted for new PW. enter it twice.
Only problem is "mount" has an O in it...

How can I use the F14 and F15 key for a shortcut?

Hi folks,
I've been trying to assign custom shortcuts to the F14 and F15 keys of my keyboard (wired, full sized type) on my Mac Pro 2008 running Mac OS X Lion 10.7.2 however every time I try to assign those keys to an app's "Record a shortcut" function I get the same error dialog from the OS:
The key combination F15 can't be used!
The key combination "F15" can't be used because it's already used by a system-wide keyboard shortcut. (If you really want to use this key combination, most shortcuts can be changed in the Keyboard & Mouse panel in System Preferences.)
(note: the same happens with F14, F13 and lower as well as F16+ work fine however)
I have looked into my system settings as the dialog suggests however there isn't a single shortcut that uses F14 or F15 anywhere in any of the shortcut groups.
If any of you have an idea of how I could "clear" or even just find out what these keys are currently being used for/by that would be super… they don't seem to do or trigger anything when I press them.
Here is another screenshot of the issue:
Note: This is not app specific, I've tried this in various apps and every time I get the same Mac OS popup.
Thanks for reading,
I look forward to your ideas and insights!

Hi,
Use the step reference to get a PropertyObject reference using the Step.AsPropertyObject. With this PropertyObject reference you can then get the values of Limits.High and Limits.Low using the PropertyObject.GetValNumber() method.
Limits.High and Limits.Low will be the lookup string for the PropertyObject.GetValNumber() method.
Hope this helps

My up and down arrows as well as page up and page down no longer work properly only when using firefox. Page up and down function more like the "home" and "end" keys as do the arrow keys.

Honestly I'm not sure if these began just after I updated FF to the current release, but it's been happening for at least 2 weeks. The arrow keys and page up and page down keys all work as if I'm pressing the 'home' and 'end' keys on my keyboard. This is only when using FF. Please contact me if you need more clarification. Thanks in advance!

Sounds that you have switched on caret browsing.

I need to reprogram the delete and enter key to the left side of a external keyboard for the ipad mini. don't need the caps/lock or ctrl key and due to an injury my daughter can only use her left hand to type. She is using a text to speech app to verbaliz

I need to reprogram the delete and enter key to the left side of a external keyboard for the ipad mini. I don't need the caps/lock or ctrl key. Due to a brain injury my daughter can only use her left hand to type. She also uses a text to speech app to verbalize all of her needs since her speech isn't intelligible any longer either. And her vision was significantly affected also, so the keyboard has to be mounted about 6 inches from her face. So to reach across the keyboard with her left hand to the right side delete and enter button is physically difficult and causes typing errors, which cause people to not understand what shes trying to say.
The best keyboard so far is the Zagg folio mini. I just had to make stickers to enlarge the letters on the key buttons.
Does anyone know how I can reprogram these two keys? Or where I can buy a wireless mini keyboard for Ipad made for lefthanders with these two functions on the left side. I have searched for days and days. It's sooooo important to me that she be able to contribute her voice again. Imagine if you got in a car accident and couldn't speak clearly any longer, but understood everything still. Thanks for any help and suggestions you all take the time to share with me. I really appreciate the kindness of strangers to help me help my daughter.

Since updating iPhoto it has ceased to open. I have tried to Hold down the Command and Option keys on the keyboard which is the suggested solution to then open a suggested solution to rebuild the library, but it does not work. iPhoto still does not open. can someone please help?
thank you

Try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
Home/Library/ Preferences folder.
2 - delete iPhoto's cache folder(s):
Home/Library/Containers/com.apple.iPhoto
and, if there is one, the
Home/Library/Caches/com.apple.iPhoto folder
3 - reboot, launch iPhoto and try again.

Z and v keys on wired keyboard not working

Been very pleased with the reliability of my 24" iMac to date, with very few (if any) problems worth mentioning till the last few days when the z and v keys on the fullsize aluminium keyboard originally supplied with the iMac no longer work?
Can anyone shed any light on why these keys refuse to work. Is it a case of throw the keyboard away, or is it a software issue?
I've rebuilt the permissions using Disk Utility which did find quite a few errors, but it didn't fix the problem of the missing Z and V buttons on the keyboard.
It may just be simply that the keyboard is worn out, but I'm no journalist and don't drink Coke or eat McDonalds burgers over the keyboard so see no reason why these particular keys have reason to stop working.
And please note, I'm typing this from the smaller wireless keypad which explains why I can still type the Z and V keys!

Thanks for the advice, I dug out my old G3 Mac keyboard, plugged it in, and it worked, so it is the keyboard that is faulty rather than the Mac - can't believe it's only lasted 5 years
Guess that it means a trip over to my local Apple Store to buy another keyboard, and knowing my luck, a few other items whilst I'm in there

E and C keys on wireless keyboard activate Mission Control

I just set up a wireless keyboard with my Macbook Air. For some reason, the E and C keys activate Mission Control at random times. I went to System Preferences > Keyboard > Keyboard Shortcuts and restored everything to default but it still doesn't fix the problem. I also can't find any direct associations between these keys and Mission Control in the Mission Control setting. Help!

In case anyone is curious, I solved this issue by upgrading to OS X 10.6.4. The brightness and volume function keys now control these functions properly.

Switch the function and control keys

Sounds like a stupid request but my life would be much simpler if my Lenova T540p keyboard had the function and control keys switched. I use the control key ALOT and having it to the far left hand lower corner would be awesome.
Thank you.

Hey there Redrabbit,
Try your BIOS. For me (Thinkpad T540p), it's in Config>Keyboard/Mouse>Switch FN and CTRL keys.

Can I swap the Function and Control keys?

Is it possible to swap the Function and Control keys?

With limitations; yes. Go to System Preferences and select Keyboards & Mouse and add your choices. Keep in mind that such chances will affect all well intended Apple commands and may end up driving you crazy!

How can I swap the Fn and Ctrl keys on ideacentre b550 touch?

How can I swap the Fn and Ctrl keys on ideacentre b550 touch?

The BIOS feature that you request already exists.
1. reboot the computer
2. press F1 to enter BIOS setup
3. config -> keyboard/mouse -> Fn and Ctrl Key swap

When I type on my macbook air I get the symbols I would get if I were holding down the option and shift keys.

I've looked at sticky keys and other stuff like this they don't seem to be the problem. I guess it is possible that both the option and shift keys are stuck at the same time, but they don't seem to be stuck at all.
I tried a restart and that didn't help and I hit the shift key 5 times....

Have you been able to fix this problem? I am having the same issue with my laptop and it seems like each letter in my keyboard performs a shortcut or function rather than typing letters

Remap the F5 and F6 keys as delete keys?

Because I make typing mistakes frequently, I use the delete key a lot. Whenever I do I crunch my wrist on its right side. I'd like to improve my ergonomics by using the F5 and F6 keys to delete. They're not used for anything else in most applications I use, and they won't cause me to bend my wrist constantly. Is there some way to get under the hood to do that?

You may have considered this option already, but a good macro-creating program (e.g. QuicKeys) can do what you describe (and lots more). The only question is whether it's worth the price ($80 to a new user). But QuicKeys can be used to replace so many hand actions--in many cases including clicks--that it likely will help you in ways besides the one you mention.
As just one example, I made a QuicKeys macro that lets me do the following: Use the mouse to put the insertion point over a word, then (with my other hand) press the tilde-accent mark key (immediately under the "esc" key in the upper-left corner of the keyboard), for which I have no other use. The word that I picked out is instantly selected and deleted--without a single mouse click. As an editor, I use that macro all the time. Other macros can be written to make screens scroll (or jump a page at a time); save files to specified folders or drives; and do many other actions that normally require using the mouse and clicking, dragging, etc.--in each case by simply pressing one or two keys. (The keys in the numeric keypad are good for scrolling or jumping a page at a time, unless you often use them to enter numbers.)

I need an option to remap reprogram or swap the ctrl and function keys on my laptop

Open letter to Lenovo
How many Lenovo laptop users does it take to get a change or option added to remap, reassign, reprogram or swap the two keys on the lower left of the keybards with each other?
The number one question I'm asked (and the first question I asked of a lenovo laptop user) was how long did it take to get used to the function key being in the wrong place on the keyboard? I did a search on the web and found a number of threads that discussed and talked about if it were possible to switch those two keys on the keyboard such as this: http://www.ashbaughonline.com/2006/08/12/thinkpad-fn-ctrl-key/ The point being is there are many lenovo laptop users that would love to have the option at least of swapping the function and ctrl key location on the keyboard and we wouldn't even complain that the key names were wrong afterwards if it were made available in some BIOS or other configuration setting.
Lenovo, how many users would need to ask for this option to make it happen?
Please add me to those who would like to see this happen and to anyone else please reply and chime in.

I have the same problem, and I really can't understand why do they do such things! I even can't get a normal answer from Lenovo about it. I like Thinkpads, they are great designed & they have a lot of unique features, most of them could be customized, exept this! Why??? I can't belive that it's so hard to remap 2 buttons using BIOS! The problem is that the FN key doesn't generate a scan code, which could be recognized by the software, i tried numerous programs to remap the FN button, but it's useless. You can do it only in 2 ways: 1. mechanical - to swap them fisically, but it's hard, dangerous & the warranty will be lost of course. 2. BIOS remapping which can be done only by Lenovo or maybe by somobody, who can hack the BIOS. So, Dear Lenovo Experts PLEASE do this feature for us, we REALLY neeed it! We need it much more than "keyboard customizer", more than "easy eject", more than "media center" becouse we use the left CTRL button every minute, working on your notebook!
