Control-U is a standard Unix keybinding for delete to start of line,
since the late 1970s, in the BSD tty driver, just as DEL is delete
previous character, and Control-W is delete word.

In emacs, control-U is a multiplier prefix, e.g. ^U^D deletes 4 characters,
^U^U^D deletes 16.

In general it's evil for GUI windows to use Control on Unix, I think,
for window functions, in that you'll get some very surprised users
when they try and delete a word and end up quitting (try ^w in the mozilla
URL bar, then click on the document window and type ^w).  But then,
lots of users got used to the idea that Backspace (^H) put you into
Help in emacs :-)
