The formatting option that I use even more than formatting text is the Format Object or Shape dialogue box to access all related formatting options in one go. While Cmd + T opens up the dialogue box to format text, I can't find any similar options for objects or shapes. It's a great waste of time to have to right click for the dialogue box or otherwise use the mouse on the ribbon.

While it's possible to create own shortcuts for most other functions, I have not been able to do so for the Format Object or Format Shape commands. I've tried dozens of command combinations to make sure it's not that the shortcut keystroke combination is already in use for another command. Still nothing.

Has anyone figured out how to do this? Any help much appreciated!
