editor vi

vi treats dash - and space   as word separators for commands such as dw and cw.

Is there a way to add underscore _ as well?

I quite often want to change part of a variable name containing underscores, such as changing src_branch to dest_branch. I end up counting characters and using s (like 3sdest), but it would be much easier to use cw (like cwdest).
