Is it possible to have a multiple letter hotkey while simultaneously having a multiple function activated within Blender? For instance, say I want the letter a to activate something, and then the letter b to do something else. So, you would hold down the "a" key, and then tap the "b" key to do that something else. This is sort of the case with say, Shift, CTRL etc that you can add to a hotkey within the keymap editor, but not exactly. There is a blank option to put in a 2nd letter (to the right of the Cmd button). My initial attempt was to map that 2nd letter to something else with the "Add New" feature, but this deactivates the first function from the double lettered (a + b) hotkey.

So what would be a use case for this? Hold down "a" to go into Edit Mode, and then tap "b" to select all vertices. Or, while still holding down "a", you decide you'd rather have all edges selected, so tap "c" to grab all edges (a,b and c being example hotkeys, not necessarily what I'd be using). Etc. Problem is it's sort of like having two hotkeys in one. I suppose it would be something akin to this answer but would be worded "Multiple functions for the same hotkey" instead.
