Keyboard shortcut for closing the color picker & other tool windows? Command + W won't work Many applications (e.g. Xcode, Pixelmator) can launch OS X's standard color picker tool window (seen below) and others (e.g. the font picker). These tool windows look almost like regular windows, but they have a shorter title bar and the three gumpdrop buttons at left are slightly smaller too.



What I'd like to know is:  How can I close such a tool window, using only the keyboard?

I've tried Cmd+W but it doesn't work for this kind of window. Rather, Cmd+W seems to cause the parent window to want to close instead. What am I missing?
Often for these kind of 'popup'/'helper' windows, the keyboard setup to hide them is the same than to show them.

I tested it in xcode for which the shortcut is :
ctrl+shift+cmd+C
It's comportement is as i expected it, it work as a toggle 'on/off' window/shortcut.

EDIT: Forgot to add one thing, you can find that shortcut easily through the help menu of each app, i usually find myself taping 'show color' to actually see the shortcut and open the panel
