Key sequences?

[test3211234]

I was looking at this key test file and saw both "a alt+a a" (separated by space) and "abcd" (no space separation) for what I assume is key sequences, as in press a then b then c then d in succession. My question is which is right and why the ambiguity? Shouldn't it be "a b c d"? Thanks

@test3211234 did you find anything useful? I'm trying to implement a very simple modal editor inspired from vim and I want to make use of commands like dd, yy etc.

Nope, was just a small question. I would say make it VSCode like and separate with pluses and separate strings with spaces
