There seem to be two different compartments in my brain for clusters of
vim commands. One is verbal. I learned ddp to reverse two lines and
xp to reverse two characters. When I did so I learned them first as
"words", and that's how they remain in my head. I can access them fast
as words, almost by reflex.
The other compartment is accretionary. I never thought of ggVG (for
selecting the whole contents of a file) as a command cluster until I saw
it in print, but when I did I recognized it at once as something I type
all the time.
It seems most effective to let my highly verbal tendencies consolidate what I have gradually learned through accretion.
