A tiny glitch, reported for the purposes of perfection. Preference - > Toolbars - > Scripts gives a list of installed addins, each with option boxes:
About, Configure, Edit
(some being unavailable in some addins).
The accelerator keys for About and Configure work, but the accelerator key for Edit does not. Neither is there any way to move the focus along the three option boxes.
Also, accelerator keys for OK and Cancel would be useful — there's already one for Apply. These options are present everywhere in Preferences.
