I'm sorry if this is the wrong place but I couldnt find a section concerning keyboards.
I'm writing this via he keyboard viewer, command shift and a few more keys are working but no letters or numbers.
anyone who has an idea?
iMac, OS X Mountain Lion (10.8.2)
I have the same problem. Function keys work, but none of the letters or numbers work, so I can't log in in hte appropriate field. I can move the icon with the mouse, (bluetooth or USB) I've tried 2 keyboards, one USB the other Bluetooth, but I can't get past the log in screen cos the letters & numbers don't respond. I can adjust the brightness using F1 & F2, and I can adjust the volume with F11 & F12.
Luckily I have this MacBook Air!
It started off as a hardware issue where I couldn't even start up. Also I can't get a hardware test to run to completion (you know, switch on whilst pressing D). Strange that the D key works for this!
Any ideas anyone?

Hey, I had that very same problem for about an hour but after panicking for very long minutes and searching for a solution, it just started working by itself! I did absolutely nothing to it, so I suggest you to wait? How long has it been anyway?
It started on Wednesday night. All programs froze when I connected a USB stick. After Force quitting all programs, the computer would restart, the loading bar got to about 20% then it just switched off. ;-(
I had a similar problem and none of the suggested troubleshooting techniques worked. I had been using the calculator widget and suddenly none of the number or function (addition, multiplication, subtraction, division, clear, etc.) keys worked. Finally, I had to go into the Manage Widgets and delete the calculator and add another one. That solved the problem.
It wasn't an accessibility problem and there was no issue with the number lock key(s). Just some weird sudden software glitch.
Entire letters and numbers set on my keyboard suddenly stopped working
