Hello, my backspace and enter keys suddenly stopped working. I have done a PRAM reset and used the keyboard viewer to see if the buttons work and they don't. The PRAM reset didn't work either

Dear All, the backspace and enter keys on my wireless keyboard suddenly stopped working. Im using OS 10.7.5 and have tried a PRAM reset which didn't work. I also used the keyboard viewer to see if the keys worked on that but they don't. This is driving me mad, can anyone please tell me what to do? It happened just after an update but this could be a coincidence. Thank you for your time

For my computers, though some of them support BlueTooth devices and accessories,
my preference and economy of standard, is to have wired USB and also use powered
USB hubs for accessories.
I've used USB wired keyboards and mouse products; and some I've bought from the
original owners who had upgraded to BT, and never used the new Apple USB model;
so I have spares of these on-hand since they seldom fail, but do work when BT won't.
{A SMC reset should not cause a problem, or seldom has; but can solve some.}
In my opinion, the wired USB keyboard is an essential accessory, if not a necessary
primary means of user access on a continuous basis. At least until the wires fail...!

Since upgrading to Mavericks my wireless keyboard keeps dropping. This stops me logging in! Can I fix this, or at least show the keyboard viewer to login?

Since upgrading to Mavericks my wireless keyboard keeps dropping. This stops me logging in! And I find I cannot reconnect the keyboard without switching the computer off. Can I fix this, or at least show the keyboard viewer to login with instead?

This is getting annoying!
The computer goes to sleep. I can wake it by pressing a key on the wireless keyboard. It thinks for a while. It asks me for the password. I can't enter the password because during that time the keyboard has disconnected from the computer. I have no choice but to hard restart the computer.
Any and all ideas welcome. Thanks in advance.

How to work the keyboard viewer to capitalize

how to work the keyboard viewer to capitalize letters

I also wish to know how to get the Keyboard viewer caps lock to work while in textedit.
The caps lock does not work for me while in any of my textedit programs.
As soon as I release the mouse button, or move off the caps lock,
the characters revert to lowercase.

[SOLVED] Thinkpad Fn keys suddenly stopped working

I'm on ThinkPad Edge 14. For some reason(s) unknown, my Fn keys stopped working after I restarted Arch a few hours ago.
I've checked the BIOS, everything is fine (no settings unchanged). I tried checking if X (I'm on Gnome 3) can still detect the keys using xev (as outlined here: https://wiki.archlinux.org/index.php/Ex … oard_Keys) and the Fn key is detected as "XF86WakeUp" witht the keycode "151", so at least nothing is wrong with the actual physical button.
What's more weird is that, I tried booting from another Hard Drive into Ubuntu, and the Fn key also didn't work (it has worked fine previously). What could be causing this?
EDIT: Even weirder, Fn keys aren't working in Windows as well (I dual boot). BIOS's still unchanged, and this started happening when I was working with Arch, so I'm quite sure this can be fixed through Arch. Problem is, I don't know where to start. How can Arch affect Ubuntu & Windows when I didn't change BIOS?

I found out the problem!
I tried checking the Lenovo forums about the problem and found this: http://forums.lenovo.com/t5/ThinkPad-Ed … d-p/323077
Apparently, it's possible that the Fn keys suddenly stopped working for no clear reason. In my case, it happened when I was on Arch, so I thought the problem was with Arch. Anyway, I updated the BIOS from Lenovo's site and everything's working fine now.
Thanks!

Buttons and enter key problem

hello,
there are a few projects of enterprise quality which I am developing in java swing. I found out through research that many or rather most people involved with java believe that swing is ready for enterprise class robust desktop applications.
so I as the team leador am starting my new projects in java swing.
I personally find that the amount of java libraries present provide a rich set of functionality and it gives big mussle power to the developers.
I am only concerned about one problem which many of you might have solved.
I find that I have to hit the space bar instead of enter key to fire an action. in languages like vb I can press enter key to fire the click events. specially in menu items I certainly don't expect my clients to press the spacebar. besides there are many people who are so used to the keyboard and enter key in particular that it will be hard or rather next to impossible to change their habbits.
how can I make the menu items work with the enter key. I mean do I need to create the code for keypress events every time I also create an action performed method? or is there a way where I can do it without extra coding.
it is just that I don't want to right extra code for enter key along with click events.
one more important note.
I am a blind person and I use the access bridge technology of java.
so when I am involved in coding, I use the same.
so may be my problem isn't a problem in the first place.
kindly provide me some help
thanks
Krishnakant.

The enter-key works on menu-items in all my applications. It did so since I started with java few years ago.
Maybe some other problem (OS-specific) ?

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.

You cannot.

Arrow keys and enter key not functioning in Firefox 3.6 when viewing PDF

I'm using Adobe Reader 9.3.0.
I have a web application that displays PDFs (using Adobe Reader) in a browser. The PDF is loaded onto the page inside an IFRAME. In addition to the IFRAME containing a PDF, the page also includes several forms, text fields, etc. For the most part this is working fine. However, I have a glitch when using this in Firefox 3.6. I'm finding that certain keyboard events are being lost and I strongly suspect that they are being swallowed by Adobe Reader. When I place focus on an HTML text field and press enter key or arrow keys, I do not get the appropriate key events. If I run the exact same test without the PDF IFRAME these key events work correctly, but as soon as I load the PDF into the IFRAME they do not. I believe the primary key event that gets lost is the keydown event. I do get the keyup event.
Again, the events work correctly up until I load the PDF onto the page.
I've verified that this error does not occur in Firefox 3.5 and 3.0.
Here is a testcase to reproduce this:
<html>

                return;
            var eventHandler = (this.checked) ? detectEvent : empty;
            document.getElementById('textfield')['on'+this.id] = eventHandler;
            //document['on'+this.id] = eventHandler;

Paste the above into an HTML document. Open the HTML document in Firefox 3.6. Check the four checkboxes. Move into the text field and press arrow keys and enter key to observe the results when it is working correctly. Then click on the "Now Load PDF" link. Press the arrow keys and enter key again and observe that the behavior has changed.
Anybody have any idea why this is happening or how to work around it?

I found a workaround!
By using an object tag instead of an iframe, all the keys seems to work fine and the PDF still renders in the page the same way.
Here's a page that works:

I have Photoshop CS, purchased many years ago for a LOT of money. Other day went to use it, got msg. "computer configuration changed, need to re-activate. Tried that for days, didn't work. Cannot call ANYONE to find out problem. Am not very computer literate, so don't understand what that means. LOVE the CS program and know how to use it, so don't want to have to learn something new. Don't know what to do. Went to all the big name stores and no one can tell me anything, like what happened to CS or what is replacing it that is the same as CS. CAN SOMEONE PLEASE HELP!!!

Yep. That's the one. Make sure to use the supplied key on the download page, not your old one.
Good luck.

There is a setting in the System Preferences for this as well that may be causing it. Go to System Preferences>General>Restore windows when quitting and reopening apps - at the bottom of the window under Number of Recent items. Remove the checkmark from that setting.
Also - if you close all of your windows when you are done with Safari - it should open to your home page.

Click off the flags of the countries you want--like if you need a British keyboard that has a British pound symbol, pick that one.
When you're done picking, them leave preferences. Now, in the upper right-hand corner of your computer, next to the date, you'll see a little flag. Click on that. You'll see all the flags you picked. Choose the one you want. Your keyboard will now give you the symbols, letters, etc. that you would get if you'd bought the computer in that country.

Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to rebuild the thumbnails. This can take 3 or 4 goes to work.
