Lets say, hypothetically, that I always forget the command :vsplit, and always think it’s :vdivide.
Is there a way to map (I’m not sure if that’d be the right thing to call it, since it’s a command) one to the other?
User defined command can only start with an uppercase letter, so you can only add :Vdivide but not :vdivide.
Add in your .vimrc
command Vdivide vsplit
