How to enable key repeat on Macbook Pro with Yosemite I would like to disable the accent characters options you get when you hold down keys. 

I have always used holding keys to repeat letters but all of the sudden it shows special characters and won't let me repeat any keys, even if they do not have special characters. I have been using Yosemite on my early 2011 MBP for a while now and this has never occurred before. Did I do some strange keyboard combination? And is there a way to turn it off, to get proper key repeats back? I have searched for this everywhere in the settings and online, but apparently it is not a known thing. 

Thank you very much in advance!
To disable the press-and-hold character palette, you could try running the following command in Terminal.app:

defaults write -g ApplePressAndHoldEnabled -bool false


Apps may need to be restarted for changes to take effect.

To reenable the menu, run:

defaults write -g ApplePressAndHoldEnabled -bool true
