I'm used to using ScreenHunter to take screenshots in Windows (http://www.wisdom-soft.com/sh/sh_free.htm). The feature that I haven't been able to find in Shutter (or any of the other screenshot tools), is the hotkey/standby. Once I start ScreenHunter, it "takes over" whatever key I've defined as the hotkey, for as long as the program is running. When I hit that key, regardless of what window has the focus, ScreenHunter displays the crosshairs to capture a section of the screen. When I release the mouse, it copies that area to the clipboard (and/or a file, depending on which you tell it to do). I thought the Gnome-Keybinding in the keyboard section of preferences might let me do that (I set "capture with selection" to <shift>f6), but it doesn't appear to do what I'm looking for.
I haven't been able to find that hotkey/standby feature in Shutter... am I missing it?
Thank you,
Irene
