I would look at a custom.mnu it can be much easier to modify than going through the CUI, you can have POP menu's and toolbars,if you can use Notepad then you can make a mnu.
This is an example of a pop menu and toolbar I have taken CIV3D commands that I often use and made a menu, I use this in the drafting and annotation workspace so dont need to change work spaces. I have a toolbar that allows surface setting with no need to go to toolspace to change say contours. It has icons for like 0.1 0.5 1.0 2.5 Off watershed. It supports multiple surfaces asks which surface to set when more than 1. Peivate mail me if want more info don't look here often.
