Apple lets users who occasionally want the use of Mouse Keys to enable/disable it by pressing Option (⌥) five times. I use Maya, so I'm constantly using the Option key to manipulate the camera, and this usage often triggers Mouse Keys. Unfortunately, this disables the rest of my keyboard (see this Apple KB page) and I can't use other helpful shortcuts. I can of course disable it again, but it's annoying when I have to do it again and again.
I went to the appropriate place in System Preferences to disable this (Universal Access > Mouse & Trackpad), but it's greyed out. I've done extensive searching and haven't found anyone with a similar problem.
Why is this happening, and how can I stop it?
com.apple.keyboard.plist
orcom.apple.universalaccess.plist
(or something similar; see note above)? I believe you will find the files in~/Library/Preferences/
.useMouseKeysShortcutKeys
, a Boolean type set to YES. I attempted to disable this, but neither the System Preferences window nor the option key act like this had an effect. Nothing else has any potential at all.
