How to make an Emote that you can toggle with a keyboard button?

I'd like to make a couple emotes that you can toggle with a keyboard button. I know how to rig, and have already made a rigged Cat model to do these emotes. I just need to know how to hook them up so that when you press a specific button, such as, for example, L for laying or T for sit, and etc. The model already has the Jump, Fall, Walk and Idle1 & Idle2 animations (Idle1 repeats 5 times and Idle 2 repeats 1 time after Idle1.) Though, I'm going to make more animations and poses in the future so that, in the future, I can code them all to be toggled with the press of a button. (If there is any coding involved, that is. and I'm sure there is.) Please help, thank you! Link to model- https://www.roblox.com/library/1544096101/Cat-v3-model-Starter-Character-do-NOT-animate-wi
