• Captures full screen, rectangle selection, freehand selection, or active window
• Can capture mouse cursor
• Allows annotation over capture, with smooth, natural mouse drawing
• Saves capture straight to desktop or to any file, sends it as email, edits, prints or sends to clipboard
• Exports as JPG, BMP, or PNG (transparent or opaque)

Thanks for this - it looks useful. Have to say that one of my favourites (though I do use several screen grab tools) is Screengrab! - which is a Firefox plugin. So, though it's got less functionality than many others, it's there at the time. (And, the version that goes with Flock lets you upload directly to Flickr if you've got an a/c there; which is handy.)
