Closed HotKey for the Matter Manipulator on Nightly

What's the hotkey for the three boxes below the middle "L/R" key?, or if there are dedicated function names for them so that I can bind them to my keyboard. Especially if I wanted to access my Matter Manipulator right now, with only a strike on one of my keys.

 

At this point I do not believe there is a keybind for those boxes.

As far as how I think they should function: The different optional functions in Super Metroid would be ideal IMO. One button cycles through them, one button clears that selection.

 

A key binding for the matter manipulator slow would be very much apprechiated. Drives me crazy having to "mouse" there.

 

I also dislike the lack of a keybind. I've had to scroll, click on, and return to previous selected item keybind to get to the matter manipulator

 

Personally, those boxes are only part of my problem with switching between items. Selecting your weapon via scrolling is like looking at something in your blind spot... But hotkeys for those boxes would be an excellent forthcoming addition!
