yesterday I accidently hit a key combo (which I don't remember) and now when I type in any app or on the command line, I have to hold down the key for about 1 second and then the key being depressed would appear. If I held down the key, it would repeat as it should.
How can I get back to being able to just type normally. How can I change the timeing for the keyboard? Any pointers here would be appreciated.
