When using vimgrep with
lv expr path/**, I like to have a shortcut for navigating the results. So I mapped the F3 key like the following:
nnoremap <F3> :lnext<CR>
Now I like to do something like the following
nnoremap <SHIFT-F3> :lprevious<CR>
But this has not the desired effect. How do I map a F-key with SHIFT?
The solution is a bit difficult. In terminals you cannot just map Shift+F3. In fact an additional line like the follwing is necessary:
set <S-F3>=^[O1;2R nnoremap <S-F3> :lprevious<CR>
But you cannot copy&paste this, see the link below in the right answer.
