alternative programs

I use AHK religiously on my Windows 10 system, I've automated nigh near everything, and I have keyboard shortcuts for everything (even including copypasta lol). Is there a tool in linux that would allow me to do the same?

Hi all and how are you! What I'm about to write, at least in part, may have been covered in the exponential forums across the Linux community so apologies if there's a duplicate. I think it would surely benefit me to have answers specific to my needs. I'm so very sorry for these newby questions...
