Some items missing from Shortcut customisation

I have a programmable keyboard and have programmed in many shortcuts to it, I am currently doing a set for the Powerclip options.

I can apply shortcuts to everything except for PowerClip, except "Select Contents" - I cannot find it in the list.

Other things that I cannot find in the list to apply a shortcut to, that are useful to me

1. Symbol>Revert to Objects

2. Select table cell only, I can select a row and column, however not a single cell.

Is there anything else I can do to apply the shortcut? Maybe a macro or script?

I contacted support but they just didn't get what I was saying.

They kept referring me to the shortcut page on the help section or telling me to find it in the menu. I was trying to make them aware that the option to apply a shortcut to those things does not exist in the program.
