I FOUND THE SOLUTION.
On macbooks, if you look on the google shortcuts (cmd+/)
and if you press cmd+f to search for shift+v
you find that the paste without formatting is set as...
cmd+option+v
HOWEVER.
IF YOU PRESS.
cmd+option+shift+v
IT
WILL
WORK.
unfortunately there is no way as far as I know to edit the shortcuts on google docs because...
well because it sucks.
however at least I found the super annoying but working way of pasting without formatting (and clicking right click and clicking left click again every single time)
