You should not be using select mode instead of visual mode. If you press `gU'
(not `gUU` since second `U' is a motion) in visual mode, it will do what you
want. Try doing `set selectmode=' and then repeat what you do. If you do not
want to use visual mode, use `<C-o>gU' instead of `gU'.

If you want to toggle upper/lower (so that `Ul' becomes `uL'), use
vnoremap <special> <S-F3> ~
if you want to toggle upper/lower based on character under cursor, use
vnoremap <expr> <special> <S-F3> ((matchstr(getline('.'), '^.', col('.')-1)=~#'\u')?
('gu'):('gU'))
