Hi Marco, there are a few commands that do not have any UI set up for them. There isn't a way to show those in the UI right now because the UI has not been developed, like the location of the button and the image for it etc... has not been done yet.

There is a full list of command names in the help file here for setting up shortcut keys:

The ones that do not have a UI button set up for them yet are listed here:
