if I'm overlooking something and this is already in the application itself, or someone has already posted about this, disregard this.
Taking screenshots with the Prnt Scr command gets tedious after a while. I swear, the application should have this. As far as I'm aware, it doesn't. Personally, I want to be able to toggle between taking screenshots with and without the HUD on screen.
Discuss?
For Mac Users its:
Command-Shift-3: Take a screenshot of the screen, and save it as a file on the desktop
Command-Shift-4, then select an area: Take a screenshot of an area and save it as a file on the desktop
Command-Shift-4, then space, then click a window: Take a screenshot of a window and save it as a file on the desktop
Command-Control-Shift-3: Take a screenshot of the screen, and save it to the clipboard
Command-Control-Shift-4, then select an area: Take a screenshot of an area and save it to the clipboard
Command-Control-Shift-4, then space, then click a window: Take a screenshot of a window and save it to the clipboard
=) I use Command Shift 3 and Command Shift 4
I'm on a Mac, and I use fn-F12 to get to the function key instead of the "make the volume louder" key (first I had to go to System Preferences -> Expose/Desktop and unbind F12, which was being used for... something, don't remember what). That way you don't need to crop out the window title.
Although those commands are nifty, I didn't know those!
If you use F12 it will save it on your desktop. About the others im not sure exactly what they do :p
F12 is the screenshot button.
Pictures are saved onto your desktop.
