Is there anything else, alternative > ways of using function that react according to button clicks ? I understand you wish to have function that recognize the button label and act accordingly. (rcd-button-insert "CLICK ME" 'action-function)CLICK ME ➜ nil (defun action-function (&optional button) (message "%s" (button-label button))) The above worked for me. (rcd-button-insert "CLICK ME" 'action-function)CLICK ME ➜ nil (rcd-button-insert "CLICK ME HARD" 'action-function)CLICK ME HARD ➜ nil (defun action-function (&optional button) (cond ((and button (string= (button-label button) "CLICK ME")) (message "Clicked me")) ((and button (string= (button-label button) "CLICK ME HARD")) (message "Clicked me hard")))) action-function Clicked me [2 times] Clicked me hard Auto-saving...done I see it works, you can have function that acts different according to (button-label) results. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
