uicontrol togglebutton turn off by enter key

Hi I am using uicontrol togglebutton, with function impoint inside and I wish to when pressing enter stop displaying point from impoint and turn off togglebutton, with all functions inside. I was searching for that but without good results. Can You give an advice with example if this possible.

Thank You

What exactly is a button with a function "inside"? Do you mean the contents of the Callback function?

I am sorry for not being precise. Yes it is called by callback.
