As titled. Usually programming tools have a way where you can just highlight a large amount of text and turn them into comments, but Notepad++ doesn’t seem to have that option. Please help, thanks!
Under Edit > Comment/Uncomment you can do this (you also find the keyboard short-cuts here), or right-click after selecting your text and choose it from there.
You need to have Choicescript defined as your language, made by @CJW found here, or it won’t work. 
Ahhhh, no wonder, choicescript must be defined first. Alright, thanks!
You are quite welcome.
