Thanks, Chris. That solves it!
I'm wondering, though, how does one know that "Option toggles the behavior from one to all" ?
Did I miss this being stated somewhere?
I don't see anything about this on the Pref screen:
Nor do I see anything about this in the SD6 Help:
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.
To change a keyboard shortcut:
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.
While the Keystroke dialog is showing:
To remove an existing keyboard shortcut:
To undo your changed keyboard shortcut:
To adopt your new keyboard shortcut:
To back out of the dialog without making any changes:
To remove an existing keyboard shortcut from a menu item, so that that item has no keyboard shortcut, select it and click Clear. This is the same as opening the Keystroke dialog and clicking Clear and then OK.
