Key press to activate animation

Hello, i’m very new to all of this and i was wondering how i can have a key press such as “R” to sheathe and pull out a weapon on my back, or if it were a smaller weapon on my side, play the according animation with said item. Also, something that may be easier, how could i tap “Left Ctrl” and have my player crouch, then a longer hold would go prone, then of course tap the buttons again to return back to standing? I have all the animations, do i have to put them into montages?

Any help is appreciated.

you ahve a anim in your projet ?

Yes im using the Movement Animset Pro, im just not quite sure how to exactly apply all these animations to the character. It seems it comes with a different skeleton aswell.
