I don't believe the OS APIs support that.  The HIGs for all supported 
desktop platforms suggest using context menus as a secondary convenience 
for items also available in the more visible menu bar.

Given that design mandate, it seems the assumption is that users can 
learn shortcuts when viewing the menu item in their primary location, 
regardless whether a subset of those items is also available in a more 
ephemeral secondary form such as a context menu.

On an implementation level, following the design mandate certainly makes 
things easier for the developer, as both LiveCode and the OS support 
keyboard triggers for visible menu items such as those in the menu bar, 
but since a popup only exists at the moment it's popped up there's no 
way to hook the event from the object.
