My keyboard has screwed up big time. I was playing Team Fortress 2 and after I closed it out, my keyboard has adopted a weird behavior. Perhaps it is TF2's fault or perhaps I somehow accidentally entered some weird shortcut while playing. Previously, Mountain Lion never suggested alternate letters for the keys that I press (i.e. û, ü, ù, ú, and ū for pressing the u key). Sometimes arrow keys, tabs, and returns seem to be sent when I am not doing so as well as the cursor jumping around. I also can no longer hold a key to repeat it. I really do not want to reinstall Mountain Lion. Does anybody have any ideas as to what will fix this? I have looked in the System Preferences seemingly everywhere to no avail.
Interestingly enough, it has to do with MagicPrefs. I changed some settings while playing TF2. I turned off "Tap to click" option in the "Point & Click" section of the Trackpad settings in the System Preferences (to enabled Taps options in MagicPrefs) and enabled and set both "One Finger Tap" settings in the "MacBook Trackpad" settings in MagicPrefs to "Left Click (Down+Up)". I noticed that it's only the first of the two that causes the problem. It seems to be sending the corresponding action at spontaneous times (when typing). For example, when I changed it to "Right Click (Down+Up)", a context menu frequently showed up. Changing the settings back to normal fixed this. This must be a bug with MagicPrefs and I may get around to submitting a bug report.
