No.  You don't have to.  Mapping key presses to functions (bind them to
commands) is a different thing.  Keys could be "1", "2", "3" and "4",
and could be mapped to "run cmd_1", ... "run cmd_4" respectively.
Then the user can define what "cmd_1" etc. does.

Best regards,

Wolfgang Denk

There are two ways of constructing a software design. One way  is  to
make  it  so  simple that there are obviously no deficiencies and the
other is to make it so complicated that there are  no  obvious  defi-
ciencies.                             - Charles Anthony Richard Hoare
