Original submission:

in the linux console with a german keyboard layout, one is unable 
to get to the directory hotlist via ctrl-\.
in this layout, \ is altgr-ß (equivalent to ralt-= on an american 
keyboard). i suspect that mc refuses to activate the hotkey, 
because it finds ralt to be pressed.
this behavior is new in mc 4.6. 

Comment 1 by Oswald Buddenhagen <ossi> at Wed 21 Sep 2005 05:19:41 PM UTC:

i came up with this hack - it just makes the right alt key not be 
recognized as an alt key at all.
i have no idea how to fix it properly - one'd have to ask the 
keymap whether the ralt is part of the keycode or an additional 
modifier.
hard-coding exceptions activated after a keymap query might work, 
but is utterly ugly. well, the code already has similar hacks to 
accomodate all types of terminals ...

I found a partial solution:
Ctrl+4 (left ctrl key + "4" on main part of keyboard)
brings mc hotlist, IF running in KDE console.
Works with my Notebook Toshiba Satellite 3000-514
and this versions: SuSE-8.2/KDE-3.1.1/mc-4.6.0-336,
and also Debian-etch/KDE-3.5.1/mc-4.6.1-1.
If it works on other machines too: should be added to help files.

More satisfactory would be an additional keybinding
- I suppose ctrl+H - that works with german
keyboard layout outside of X, too.
Until now, outside of X I must use menu entry,
have no keybinding for accessing the hotlist.
Only "add to hotlist" Ctrl-X H works.

Double for #195. Also blocked by #212.

relaying this to #212 isn't particularly nice. nobody wants to go through extensive configurations just to get the keyboard working in a particular application. am i expected to do that with every independent account i use mc on (4 as of now)?

both the linux console and x11 would actually allow querying the keyboard map, and for other terminals modifier querying isn't done in the first place anyway.

the much simpler approach would be making my hack an option. actually, FAR has exactly such an option ... not that i like the idea too much.

#212 allow to create common configuration schemes that will be nice for all (or about it) with lower costs. Oh, yes, it was described in #195. ;)

So for that issue, we will need hot-key in "classic" schema:
C-x prefix seems to be reasonable and consistent.
What do you think about "C-x ."?

this still doesn't solve the problem - it works around it. kinda backwards to have to learn new hotkeys to "fix" a regression, don't you think?
fwiw, i hate those c-x "escape sequences". i feel lucky that none of them is part of my regular workflow. as opposed to c-/.

Are you sure that is not terminfo issue?
Can you check it now with old version of mc
and acknowledge that is work in your current environment?

not every keyboard problem is a terminfo/termcap problem ... ;)

Yes, I know it.

But it's very old bug and we need to be sure that
we can check correctness of fix in current environment.

So, can you check it now with old version of mc
and acknowledge that is work in your current environment?

Ok, I can check it, ([] - keystroke):

setxkbmap -layout us,de
echo "[C+vC+\][space][change to de][C+v C+RAlt+-]" | od -c

and also in vim.

I checked it in my environment.

All work in mc builded with ncursesw, so it's slang bug.

Please, write bugreport to slang developers or your distro maintainers.

complete fail on your side. the ticket title clearly states that this is *not* about an x environment.
this is *solely* about the games mc plays with modifier keys and has *nothing* to do with slang, ncurses or the key translation of either. the proof is trivial: just "ssh localhost" to make mc think it's not running on a local linux console any more and thus skip trying to determine the modifier state.
