I really don't agree with saving keypresses being a useful metric, since auto-completion is a thing and code is read significantly more often than it is written. I am also a staunch opponent of abbreviations being used for variable names.

But I will say that I don't mind abbreviations in keywords, since well, you need to learn the meaning either way.
And yeah, I've come to somewhat like them being used for keywords, since it reduces visual noise where it really isn't useful, and it distinguishes keywords from actual code.
Ultimately, keywords are just syntax where letters were used instead of a symbol. You do read them like a symbol, so if they don't look like a real word, that seems to work quite well for my brain.
