I would like to map <Tab> in select mode to indent my selection.
So I have this:
$ vim -u /dev/null
:set nocompatible
:behave mswin
:xnoremap <Tab> >gv
:xnoremap <S-Tab> <gv
:snoremap <Tab> <C-g>>gvV<C-g>
:snoremap <S-Tab> <C-g><gvV<C-g>
The idea is to switch to S-LINE or V-LINE when identing. The problem with the above mapping is the V will toggle between VISUAL -> V-LINE -> NORMAL.
How can I correct these mappings?
In visual mode, you only need one > to indent. >> is the normal mode command. Also, V turns a non-linewise selection into a linewise one, but if the selection already is linewise, visual mode will end. Better drop that. These changes result in:
snoremap <Tab> <Esc>gv>gv<C-g>
Actually, you can further simplify; there's no need to leave select mode and then restore the selection in visual mode via <Esc>gv; just use <C-g> to switch from select to visual mode:
snoremap <Tab> <C-g>>gv<C-g>
>>. I have completed my question and your answer is no more valid. I hope you don't mind.

<S-Down>, when you go on linewise mode, you actually select two lines instead of one...

> is linewise, anyway, regardless of the selection type.

:map <expr>, and check the output of visualmode() if it is already linewise (i.e. returns V), and only if not force linewise with gvV.
