Script Debugger permits you to customize (change) the keyboard shortcut for any menu item, including Clippings and Scripts. The Key Bindings preferences pane is where you do that.

The table lists all of Script Debugger’s menus and menu items, in hierarchical outline format. By clicking the disclosure triangles (or by double-clicking a line), drill down to the menu item whose keyboard shortcut you’d like to alter. Click the Set button, or double-click the menu item listing. The Keystroke dialog opens.

With the Keystroke dialog showing, type a keyboard shortcut. It must involve at least the Command key or the Control key, or be a Function key (F1, F2, etc., plus Home, Page Up, and so on). It may additionally involve any combination of modifier keys (Shift, Control, Option, Command). Script Debugger warns you if you type a keyboard shortcut that is already in use by another menu item.

To remove an existing keyboard shortcut from a menu item, so that that item has no keyboard shortcut, select it and click Clear.
