Thanks. Interesting idea. But if i am not mistaken, this will fail, if
there are tabs in front of the visual selction.

My current idea is to map a key like this:
xmap <silent><expr> key ":\<c-u>let g:curswant=".getcurpos()[4]."\n"
and then run :norm gvkey

This works, but is slightly clumsy...

Made me think, if visualmode should perhaps return '^V$' in this special
case?

Best,
Christian
