There’s a shortcut for all of the basic math functions except subtract. I would imagine that holding “S” with a left click (like the other math functions use “A”, “D” and “M”) would do this but instead spawns a scalar parameter? It would probably make more sense to hold “Shift+1” for a scalar parameter seeing as “1” spawns a scalar constant.
I cant be the only one who forgets “S” doesnt spawn subtract and ends up spawning a parameter that is instantly named “ssssssssssss”.
use ‘S’ for subtract and push scalar-parameter to 5 (it’s after the 1,2,3,4 vecs…)
or
use the minus-key ‘-’ for subtract. it moves it off the left-hand-resting position, but symbolizes well
EDIT: FYI for anyone that reads this, as of at least 5.3, you can still right-click and hit the minus key to get to subtract, but I still would rather a hotkey to hold+mouseclick like the other basic operators
