I love the ability to customize keybindings in 4.7. However, I've noticed
some keys cannot be bound because they aren't recognized properly by
Midnight Commander. When you hit an unrecognized sequence, mc will simply
skip the escape sequence up to a point and print the rest of it.
I'm using Konsole, set to the xterm (XFree 4.x.x) keyboard, and $TERM is
xterm. These are the key combinations that produce escape sequences but
aren't recognized by mc. Everything else either works, or doesn't produce a
distinguishable escape sequence so I won't expect it to work except if you
use X. I've listed the escape sequences produced by Konsole (as seen with
cat >/dev/null for example) and the gibberish text written by mc after
failing to recognize the escape sequence:
Shift+Tab:
Konsole: ^[[Z
mc ignores the key and prints: Z
Alt+function keys:
Konsole: ^[O3P ^[O3Q ^[O3R ^[O3S ^[[13;3~ ^[[17;3~ ^[[18;3~ ^[[19;3~
^[[20;3~ ^[[21;3~ ^[[23;3~ ^[[24;3~
mc ignores the key and prints: 3P 3Q 3R 3S 13;3~ 17;3~ 18;3~ 19;3~
20;3~ 21;3~ 23;3~ 24;3~
Alt+Shift+function keys: Same but 4 instead of 3
Control+function keys: Same but 5 instead of 3
Control+Shift+function keys: Same but 6 instead of 3
Control+Alt+function keys: Same but 7 instead of 3
Control+Alt+Shift+function keys: Same but 8 instead of 3
(Function keys and Shift+function keys work properly)
Alt+Insert, Delete, Home, End:
Konsole: ^[[2;3~ ^[[3;3~ ^[[1;3H ^[[1;3F
mc ignores the key and prints: 2;3~ 3;3~ 1;3H 1;3F
Alt+Shift+Insert, Delete, Home, End: Same but the last number is 4 instead
of 3
(Ctrl+Insert, Delete, Home, End surprisingly work)
Ctrl+Shift+Insert, Delete, Home, End: Same but the last number is 6 instead
of 3
Ctrl+Alt+Insert, Delete, Home, End: Same but the last number is 7 instead of
3
Ctrl+Alt+Shift+Insert, Delete, Home, End: Same but the last number is 8
instead of 3
I'm using the mc package from Debian sid, version 3:4.7.0-1 on AMD64 with
the following --version information:
GNU Midnight Commander 4.7.0
Virtual File System: tarfs, extfs, cpiofs, ftpfs, fish
With builtin Editor
Using system-installed S-Lang library with terminfo database
With subshell support as default
With support for background operations
With mouse support on xterm and Linux console
With internationalization support
With multiple codepages support
Data types: char 8 int 32 long 64 void * 64 off_t 64 ecs_char 8
Any tips on how to make these keys work? Which terminal emulator, keyboard
setting and $TERM value work best for you? Should I create a ticket in the
mc website about this?
Thank you very much in advance,
~Miguel
