how a function is evaluated?

how a function is evaluated?

[A Soare]

When I associate a function with a keybinding, that function is called using funcall from command-loop function when I press a function?


Thanks.

Basically, yes.

Actually, the primitive in lisp to call functions is apply, so it is
possible that it doesn't go thru funcall, but thru apply.

But in emacs, there are other "primitives", and I guess it's
call-interactively that is used to call commands, from keybindings.


Note that you cannot bind to a key a random function in emacs.  You
can only bind (and actually call it), a _command_, which is a function
that has an interactive declaration.
