OS X screen capture: Cmd-Shift-Ctrl-4

I've been doing image capture the OS X way, using Grab.app.

I just learned that ancient Classic methods still works, and it still creates a PICT image. Not much understands PICT any more, but Omni Outliner Pro still does.

So hit Cmd-Shift-Ctrl-4. Highlight the area to image. The PICT is now in the clipboard. Paste it into OO Pro.
