Lisp to use as Esc Button

Is there any possibility to use lisp to neutralize grips. instead of pressing Esc Key.

What is the problem with ESC button ?

ai_deselect

Unfortunately, you'd be adding a step were you to do so, as any LISP command will require the keyboard entry, and Enter (or Right Click), unless used in a Toolbar, or Ribbon button.

Another example:

(defun c:` () (sssetfirst nil nil))
