If you see that selected icons, text fields or other interface controls have a black border surrounding them and/or you hear voices, you're not going crazy! For example, you may click Finder and see Empty Trash
as well as Empty trash...
(Note that one of them has an ellipsis.) VoiceOver
has probably been activated by accidentally pressing its keyboard shortcut.
Go to System Preferences
> Universal Access
and turn VoiceOver
off, either by checking the appropriate button or by pressing that key combo again (you'll see the key combo next to VoiceOver in the Universal Access preference pane).
If this becomes a frequent (and annoying) occurrence, you can disable that keyboard shortcut by going to System Preferences
> Keyboard & Mouse
> Keyboard Shortcuts. Written by jchuzi, dianne and dkmarsh with contributions from artie505 and joemikeb in Turning VoiceOver off.
