Vim-like control with xmodmap
The implementation of the Vim-like control described in the previous article has a couple of significant drawbacks: it fits only to the GTK environment and a modifier key is required to move the cursor through the edited elements. It turns out, in general, not quite and Vim-like, as was rightly noted in the comments. Therefore, it was decided to describe his experience in building a keyboard-like keyboard environment using xmodmap and the command shell.
The first thing to do is create a directory for xmodmap resource files, for example ~ / .keytoggle.
The second is to remove the current keyboard layout:
')
Next, create a file
All the bindings are described in the comments, I will note only that in my case the REMAPs Ctrl-CapsLock, Esc- ~ and some more personal reassignments are used.
Actually, the switching of input-editing modes is performed simply by performing xmodmap with the resource we need. You can hang on a couple of hotkeys, and you can write a script like this:
The call “kt t” changes the mode, without arguments - gives to standard output a state that can be displayed in the status line of the window manager, via osd_cat or any other notifier to taste. For example, like this:
And the final chord - hang up switching modes on the hotkey. For example, my switch was assigned to <Super_R>:
Such an implementation does not depend on the used toolkit, but it will also greatly please Vim lovers, who have to work a lot with Windows via rdp, I think.
Why did I give up on all this? Virtually all the software I need every day has an out-of-the-box Vim style control. As a result, the need for additional keyboard mode simply disappeared. It was replaced by the mod1 + [hjklqw] combinations described in the previous article in some input fields (webkit, dwb command line). By the way, I use these shortcuts when editing in Vim - sometimes it's faster than changing modes.

Actually, the switching of input-editing modes is performed simply by performing xmodmap with the resource we need. You can hang on a couple of hotkeys, and you can write a script like this:
~ / bin / kt
#!/bin/bash DIR="$HOME/.keytoggle" function toggle(){ if [ -e $DIR/lock ] then xmodmap $DIR/input-keymap.rc rm $DIR/lock else xmodmap $DIR/control-keymap.rc touch $DIR/lock fi } function show(){ if [ -e $DIR/lock ] then echo -- else echo -- INSERT -- fi } case $1 in t) toggle;; *) show;; esac The call “kt t” changes the mode, without arguments - gives to standard output a state that can be displayed in the status line of the window manager, via osd_cat or any other notifier to taste. For example, like this:
~ / .ion3 / main / cfg_statusbar.lua
mod_statusbar.create{ screen=0, pos='bl', fullsize=true, systray=true, template="%date".. "[ %>workspace_name ]".. "[ %exec_xkb ]".. "[ M: %exec_mounted ]".. "%filler".. "%>exec_lt" } mod_statusbar.launch_statusd{ load={ update_interval=10*1000, }, date={ date_format='[ %H:%M ]', }, exec = { lt={ program = "mps s", retry_delay = 3 * 1000, }, xkb={ program = "kt", retry_delay = 1 * 1000, }, mounted={ program ="fmounted", retry_delay=2 * 1000, }, } } And the final chord - hang up switching modes on the hotkey. For example, my switch was assigned to <Super_R>:
$grep 'kt t' ~/.ion3/main/cfg_ion.lua kpress("Super_R", "ioncore.exec_on(_, 'kt t')"),
