3ds Max :: Assign Keyboard Shortcuts For Different Selection Sets Functions / Commands?

I am trying to find a way to assign keyboard shortcuts for different selection sets functions/commands.

I failed to find selection set commands in customize user interface menu. seems that they named it in a manner so that people cant find them when they simply look for "selection" or "set" or "create selection set" or "make selection set" .

what I need is:

1. when I select a group of objects I want to make them a selection set with one keyboard shortcut. (to go to the sets menu window and press that "create a selection set" button is too time consuming. I am also aware that just writing a letter to the selection sets dialog creates a set but still I want that shortcut.)

2.select an object and immediately jump to the whole selection set with a keyboard shortcut. or toggle through selection sets.

3.delete the active selection set with one keyboard shortcut.

are these functions available as native commands in customize user interface?should I go looking for a maxscript ?
