Solved Binding Ctrl+Left/Right to back/forward-word outside X

fscorrea · Feb 20, 2017

The usual solution is editing $HOME/.inputrc for bash and $HOME/.cshrc for csh. These are mine:

.inputrc

Code:

"\e[1;5C": forward-word
"\e[1;5D": backward-word

.cshrc

Code:

# $FreeBSD: releng/11.0/share/skel/dot.cshrc 278616 2015-02-12 05:35:00Z cperciva $
#
# .cshrc - csh resource script, read at beginning of execution by each shell
#
# see also csh(1), environ(7).
# more examples available at /usr/share/examples/csh/
#

alias h        history 25
alias j        jobs -l
alias la    ls -aF
alias lf    ls -FA
alias ll    ls -lAF

# These are normally set through /etc/login.conf.  You may override them here
# if wanted.
# set path = (/sbin /bin /usr/sbin /usr/bin /usr/local/sbin /usr/local/bin $HOME/bin)
# setenv    BLOCKSIZE    K
# A righteous umask
# umask 22

setenv    EDITOR    vi
setenv    PAGER    more

if ($?prompt) then
    # An interactive shell -- set some stuff up
    set prompt = "%N@%m:%~ %# "
    set promptchars = "%#"

    set filec
    set history = 1000
    set savehist = (1000 merge)
    set autolist = ambiguous
    # Use history to aid expansion
    set autoexpand
    set autorehash
    set mail = (/var/mail/$USER)
    if ( $?tcsh ) then
        bindkey "^W" backward-delete-word
        bindkey -k up history-search-backward
        bindkey -k down history-search-forward
        if ("$TERM" == "cons25") then
           bindkey "^?" delete-char
                else if ("$TERM" == "linux") then
                    bindkey "^[[3~" delete-char
                else if ("$TERM" == "xterm" || "$TERM" == "xterm-clear") then
                    bindkey "^[[3~" delete-char
                    bindkey "^[[5C" forward-word
                    bindkey "^[[1;5C" forward-word
                    bindkey "^[[5D" backward-word
                    bindkey "^[[1;5D" backward-word
                    # bindkey "\303\277" backward-delete-word
                endif

    endif

endif

That works fine if running X, but fails otherwise. Note that only these two specific bindings do not work. For example, the Delete key won't work in csh without a bindkey "^[[3~" delete-char. However, once .cshrc is properly edited, ths issue is fixed regardless of running inside X or not.

However, Ctrl+Left yields the "^[[1;5D" ("\e[1;5D") CSI only in X terminal emulators. In console it's bound to "^[[D" which is the same as pressing the Left arrow alone, with no modifiers. As such, binding "^[[D" itself can't be a solution since it would conflict with "normal" backward-char cursor moving. Likewise, Right/Ctrl+Right present similar issues.

It happened on my GNU Linux as well and I managed to fix it. First, I got the arrows and the letter 'b' keycodes through showkey. So far, ~~cat or even~~ xev could serve the same purpose in FreeBSD.

I apologize for mistaking. cat will do the same as C-v (outputs "^[[D" instead of pressed keycode).

Then I dumped current keymap through dumpkeys -1 and checked the Alt modifier for 'b'. The entry read Meta_b, so I created a custom.kmap file like follows:

Code:

keymaps 0-127
control keycode 100 = Meta_b

Since Meta_b was referring to the letter 'b' key with the alt modifier, that's just like saying Alt+b, or M-b - which happens to be default keybind for backward-word. Done.

I tried to adapt this solution. kbdcontrol -d gave me the keymap just like dumpkeys would. All entries for keycode 100 (Left arrow) are set with "fkey58". I tried changing it to a quoted CSI, other than "^[[D" which I can't remap. I tried both"^[[1;5D" and "^[[5D" as shown in my .cshrc, then finally "^[b" (Alt+b as listed in csh with bindkey). After changing the corresponding entry I reloaded the custom keymap with # kbdcontrol -l custom.kbd, but nothing has changed. Regardless of what was replacing "fkey58", testing with C-v printed the same "^[[D" all the time.

As a last resource I tried # kbdcontrol -f 65 "echo -e \e[5D" and replace fkey58 with fkey65 in Control column of keycode 100. It didn't work. Actually, I later changed it to # kbdcontrol -f 65 "echo TEST". Still, instead of echoing "TEST" on tty, it printed the usual "^[[D".

It seems Ctrl+Left won't change regardless of what I do. Even changing it to a free function key (fkey65) and assigning a simple command such as echo TEST won't work. Still, as far as kbdcontrol(1) goes fkey10 can be set to run telnet. What am I doing wrong here? M-b and M-f works just fine in virtual console. Sure I could just use these and forget about this matter, but I don't think a workaround this would be too complex. I'm just missing something.

I'm posting a custom.kbd with line for keycode 100 already modified. I saved default keymap with kbdcontrol -d > default.kbd but it's exactly the same, except for reading fkey58 where I put fkey65:

Code:

#                                                         alt
# scan                       cntrl          alt    alt   cntrl lock
# code  base   shift  cntrl  shift  alt    shift  cntrl  shift state

I have further considerations to add:

BSD showkey differs from its Linux version and shows the raw value returned by a key press, like cat, and not the actual keycode;
X and virtual console probably don't share the same scancodes so xev is no longer an option. I'm looking for alternatives;
I tried kbdcontrol(1) kbdcontrol -f 10 "telnet myhost" example, to no avail. I tried hitting each of my keyboard keys, randomly, but never got the error message for telnet-ing invalid hostname. I tested keycode 68 according to xev (F2) as well but failed, as expected for I've already mentioned they're not the same;
kbdmap(5) says:
Code:
```
You can uset the -f option of the kbdcontrol(1) utility to assign arbitrary strings to function keys.
```
Which pretty much solves the problem if control chars (ESC) are allowed on string, or if it's read as a command and used for runnning e.g. echo or printf

What I still don't get is why kbdcontrol(1) example didn't work. I'll try changing an obvious key like 'a' or 'b' to print fkey10 as a symbol just to make it sure.

The example with .inputrc only work, if you put

Code:

export INPUTRC=~/.inputrc

in .bashrc.

I have this line in $HOME/.profile.

This thread solved the issue: Thread 57444

Fetch base if you don't have /usr/src;
Check diff on this post. Six source files are to be "patched";

There is a line which must be fixed:

Rebuild and reinstall GENERIC then reboot:

Code:

# cd /usr/src/
# make buildkernel KERNCONF=GENERIC
# make installkernel KERNCONF=GENERIC
# reboot now

$ kbdcontrol -d > custom.kbd or just make a local copy of /usr/share/vt/keymaps/your_default_keymap.iso.kbd;
$ sudo pkg install misc/kbdscan or build it from misc/kbdscan ports;
$ kbdscan to get the Left/Right arrow keys scancodes then check their corresponding entries in custom.kbd;
Change fourth column to "fkey78" for the Left arrow key. Do the same for the Right arrow key using "fkey79";
$ kbdcontrol -l custom.kbd to load your customized keymap;
If necessary, $ kbdcontrol -F will load default function keys;

Done.
