[racket] Custom Keybindings - Editor Insert Poofed

What happens when you type control-a (with the menu keybindings turned
off). That should do a similar thing to what your keybinding does (ie
call a text% method of that first argument without checking to see it
is a text% object). If it works, it will move the insertion point to
the beginning of the line.
