ShortcutBar shortcut keys

You can't directly associate a shortcut key with shortcutbar items.  You would have to create your own method to determine which key combinations have been set.  One thing you could do if you are using commandbars, you could create some "dummy" controls and associate the shortcut keys you want with the "dummy" controls.   Then in the Execute event you can do something like :
wndShortcutBar.Selected = wndShortcutBar.FindItem(SHORTCUT_CALENDAR)

Let me know if you want me to explain further on this idea or I could modify one of the samples and send it to you.
