- # This spawns a PIN entry terminal on top of a tinted screenshot of the
- # current display's root window. The display for spawning the terminal can
- # be predefined, in which case both the current and the predefined display
- # will show the screenshot.
- #
- # The purpose of the screenshot, aside from looking nice, is to prevent entry
- # of the PIN into the wrong window, e.g. by accidentally moving the cursor
- # while typing. If necessary, the screenshot can be closed by sending 'q',
- # 'Q', or ctrl-c while its focused.
