Ctrl-Fx and Shift-Fx keyboard shortcuts don't seem to work

[ilson]

1. Create a file ~/.config/mc/mc.keymap and put these lines into it:

[filemanager]
Find = ctrl-f7; shift-f7

2. Open MC and try pressing Ctrl+F7 or Shift+F7. Neither shortcut seems to work.

OS: Arch Linux
Terminals I tried: UXTerm, GNOME terminal, GNOME console
Midnight Commander 4.8.31.

Additional info:
1) F9 -> "Command" shows (among other things) "Find file C-F7", that is the "mc.keymap" file is found and parsed.
2) Both Ctrl+F7 and Shift-F7 combinations work in Vim - for example, mappings like "map <C-F7> iCF7" and "map <S-F7> iSF7" work.

Please let me know if you need additional info.

@andrew_b: Thank you, the method described at ​http://www.midnight-commander.org/ticket/2467#comment:6 works for Alt-Fn and Ctrl-Fn for me, but not for Shift-Fn for some reason...

For people having that same problem: turns out for Shift-Fn keyboard shortcuts to work they must be specified as "f1n" in mc.keymap. For example, Shift-F7 should be specified as "f17" (and not "shift-f7").
