This page contains options that affect the behavior of toolbars and menus.
Alt + left-click to edit toolbar buttons: Lets you enter Customize mode and bring up the Function Editor for a button in one single action, by holding the Alt key down and clicking the button with the mouse.
Having this option on means you can't use the Alt key with any buttons that use qualifier keys to change their behavior. If you want to keep the normal Alt behavior and create an alternative hotkey, see the Toolbar CLICKTOEDIT command.
Minimize Customize dialog opened via Alt + left-click or Toolbar CLICKTOEDIT: Minimize the Customize dialog automatically when opened via the above option or the Toolbar CLICKTOEDIT command.
Makes it so only the Function Editor for the button you clicked is shown. If you click OK or Cancel in the function editor, and you have not edited another button or activated the Customize dialog, the Customize dialog will automatically close when the function editor closes. This lets you make quick changes to existing buttons without the Customize dialog getting in the way.
Related: The Prefs CUSTOMIZE MINIMIZE command can be used to open Customize mode with the dialog minimized, without having to open a button editor at the same time.
