Unwanted OS X window
By accident, my big fingers hit some key combo that has resulted in a perculiar window opening that I can not close. It is in a white frame, with black background and white letters. It seems to be an OS window that shows commands, such as switching from program to program or selecting a file. On a web site, there is an additional window that outlines the selections that I make.
I can not figure out how to get rid of this annoying window.
Any one have any insights or advice?
