138. nmap <tab> v>
nmap <s-tab> v<
When mappings and menus are defined with
the |:vmap| or |:vmenu| command they work
vmap <tab> >gv
both in Visual mode and in Select mode.
When these are used in Select mode Vim
vmap <s-tab> <gv
automatically switches to Visual mode, so
that the same behavior as in Visual mode is
effective.
