Edit Annotation Tool - Menu Options - Getting at Convert to Multi/Single Part tool

DavidPlume1

Hi Everyone,

I'd like to create some short cuts to point at the Convert to Multi/Single part commands on the Edit Annotation Tool.  These commands are available in the Advanced Editing Commands list but become inactive when posted on toolbars.

It would be very handy to associate some keys or similar short cuts to these commands while in an edit session.  I thought that the code to get to these properties would be pretty "easy" to wire up in VBA or a .NET addin. 

I've not even been able to find the interface these properties sit on.  Can anyone offer some insights into which objects manage Annotation Properties at this level?

Thanks
David

OK I've worked out what object(s) manage(s) single/multi part settings. 

This doesn't explain why the interface disables the basic command when posted on a toolbar but does give you a way to add this functionality to your own controls.

You derive IMultiPartTextElement from IElement:
