As Dan said, you can bind the command to a key in the
mode's keymap.  If the command is appropriate only for
the mode then you can also change its code so that if
it is ever invoked outside the mode (usually tested
using `derived-mode-p') then it does nothing, or it
shows a message saying it is only for the mode, or it
raises an error saying the same thing.
