We can call them "toggle buttons" if that sounds you better.
"Toggle" buttons is what we have now. Lae'zel has a melee weapon equipped, I click "Menacing Attack (Ranged)" and she "toggles" to her ranged weapon.
However, I agree with you and @mrfuji3 that there should be a way to combine manoeuvres with other skills or items, such as special arrows. However, it wasn't the original scope of the thread, and looks like a pretty big expansion of it.
I would also like a fixed UI element which is always visible. It should be possible to put all this stuff onto the action bar, along with rage and spell slot selectors. After all, Gale has his Arcane Recovery there (which opens a big beautiful panel with a single button on it), and Shadowheart has a Channel Divinity button there.
