I can't "remap" <Shift-F4> key

[ludo]

Hi,

I'd like to map ":cprev" to <Shift-F4>
I use (in normal mode)
:map <S-F4> :cprev <CR>

But when I press the <Shift-F4> key, Vim displays the message 'Already
an oldest change'
Maybe, <Shift-F4> is a "reserved" combinaison key for Vim ?

if I try
:map <F4> :cprev <CR>
that works

what is wrong ?

Hi,

you probably have a buffer-local mapping like

:map <buffer> <S-F4> u

defined somewhere. You can check this with

:map <S-F4>

This should show something like

<S-F4> @u
<S-F4> :cprev <CR>

The mapping with the ampersand is the buffer-local one and this takes
precedence over the second one.

If you want to know where the first mapping was defined execute

:verbose map <S-F4>

and you get something like

<S-F4> @u
Last set from c:\map_u.vim
<S-F4> :cprev<CR>

Regards,
Jürgen

unfortunately, when I execute
:map <S-F4>
Vim displays 'No mapping found'

and ':verbose map <S-F4>' also displays 'No mapping found'

Maybe, the problem is around the SHIFT key
When I try to use Fx key (F2, ... F12) with the additionnal SHIFT key
for the :map function, it's failed
:map <F4> :do_something
:map <F...> :do_something
:map <F12> :do_something
all succeeded

but when I try
:map <S-F4> :do_something
:map <S-F...> :do_something
:map <S-F12> :do_something
all failed :-(

Check that the operating system isn't getting in the way: go to insert
mode and hit Ctrl-V Shift-F4. If you get <S-F4> then I would expect
the mapping to work.

which system are you on? And what do you see when you enter

<C-V><F4>

and

<C-V><S-F4>

while you are in insert mode?

I use Vim 7.2 for cygwin with XP

I have tried on my Debian with Vim 7.1 and the result is similar (:map
<S-F4> doesn't work)

when I hit 'Ctrl-V Shift-F4' => Vim displays ^[[26~

when I hit 'Ctrl-V F4' => Vim displays ^[[[D

Hm. What is 'term' set in each case. If it is set to different values
(let's assume "cygwin" and "xterm" for the sake of argument; but replace
them below if different), you should be able to cure the problem as follows:

if &term == 'cygwin'
set <S-F4>=^[[14~
elseif &term == 'xterm'
set <S-F4>=^[[[D
endif

where ^[ is obtained by hitting Ctrl-V followed by Esc.

Alternately, use gvim rather than Console Vim: there, your F keys ought
to be detected correctly.

Best regards,
Tony.

effectively, ':map <S-F4> :do_something' works fine with gvim
and I will try to customize later my .vimrc with the &term variable

thanks for your help
