How do i make more functions on one keybind.

I need help with Keybinds. Am trying to do abilities on one keybind [R] but it would work somehow like this: You have 2 weapons in the mod one being katana the other spear now when you press r while the katana is in you'r hand it does for example dash ok, but then i need the same keybind to make strong slash on spear but you cant since you can use the keybind on one thing. So my question is if its possible to make one keybind have more abilities for each weapon.
