Caps lock button works in reverse!

So my caps was working in reverse but I discovered that I must have clicked 'option and caps lock' instead of 'command and tab' to switch between screens. When I clicked on 'option and caps lock' again it all went back to normal. Hope this helps for other people. (Macbook Pro Mid 2014 Retina)

I think in an earlier post you meant that someone fixed thier problem by holding down CTRL+Shift+Cap Locks.

I recently had the same problem and solved mine by typing tHANKS into Microsoft Word. It automatically corrected the typo and synced my keyboard in one go. Give those a try.

I haven't found much on the web about this. I did run across one post of the same problem and that person said she could fix hers by hitting Caps Lock, then Shift, then Caps Lock again.

Do you have any keyboard-related apps that might be causing this problem?

I don't know if it will do anything but what happens if you open Keyboard Viewer (on right side of the menu bar) and click on the Caps Lock button in the viewer? You might first have to go to System Preferences/Keyboard to turn on "Show Keyboard Viewer in Menu Bar".

Same problem on MacBook Pro 13" mid-2009 (french keyboard) and OSX 10.9.3:

Note: this happens only after a sleep time (not necessary long)

Holding down CTRL+Shift+Cap Locks did not works for me

You saved me, option + caps worked for me

Interesting. When I use the Keyboard Viewer, the light on my caps lock key turns on/off accordingly.

So, what happens if you have the caps lock LED lit up then go to Keyboard Viewer set caps lock to be on? Does the caps lock key and its LED work correctly after that?
