I can no longer get any keys to continue to do a series of letters by keeping the key depressed, this means repeating the key stroke for as many times as you need - the only exception is the full stop. I have tried going into system preferences and setting the keyboard to fast repeat to no avail. Any ideas anyone? This has happened on my MacBook and my iMac and doesn't matter whether the keyboard used for the iMac is wired or wireless.
I will update my strap line following this post.
