How do I add keyboard recognition?

I already managed to make it so that the keys i press are recognized, but i think the way it was made it's not efficient as i used an event for each letter, what would you recommend so that letters are recognized using less events?

Also, after that i'd like to add a system which would randomly show words on screen and you have to type every letter in order, how would you approach that?

It really depends on how you're doing.

I'm not sure your experience level, but you could store the state of each key in a dictionary object

"r" -> on

"s" -> off

...

"shift" -> on

Here is little demo with Keyboard and CHR$ codes work it out from that
