Spamming /laugh, /dance, /joke, /taunt

Hi, everybody! My name is HeroineSam. I've been playing this game for a while now (3-4 years?) and I am level 30. However, I do know very little about the quality of life parts of league (i.e. the title's contents) and I would just like to ask the veterans, knowledgeable new-comers, and anyone else of this (mostly) wonderful community to teach a relatively old dog new tricks. It'll help me expand my repertoire as a League player and connect in a different way to the game. TL;DR (whatever that actually means) I would like someone to teach me how to spam the emotes of a champ so that it looks like they're twitching/spasming. If you have no earthly idea what the hectagon I'm talking about: reference the twitch stream of Kled's gameplay some 40 minutes in (maybe, I'm not sure) or watch some of Brofresco's videos. Thank you in advance!

P.S. I'm sorry for taking sooo long to get to the point, I do have a habit of adding a whole lot of fluff into my works. So excuse the bunch of useless stuff that just takes up space above.
