The standard examples of bindkey assume you're binding editor commands
rather than normal commands, i.e. something that helps you edit a
command line.

To bind a command to a keystroke, you need the "-s" option to bindkey.
However, note it's doing something rather different --- basically just
dumping the keys you type into the command line.  One idiom for running
"foo" this way is to use ^q to ensure there's nothing else in the buffer
(if there is, you don't lose it, you get it back after running foo), and
put a newline at the end.  Luckily you can use the same abbreviations
for keys as in the keystroke part of the command:

bindkey -s '<keystroke>' '^qfoo\n'

This assumes ^q is bound to the editor command push-line.  You can
remove the ^q if you only want to use this on an empty command line.
