require('keychord') in the file you use for bindings or in rc.lua
local keychord_mode = require('widget.keychord_mode') and add it into your wibar

Both files will need some modifications to remove the specifics of my config, like module.screens, util.markup and util.spacer. But those do not provide any relevant code to the keychord functionality.

I tried this but this line 3 in keychord.lua gives me an error; local global = require('global')
'module not found', where does that come from and how to I add it?

Global just contains the desired modkey as a string. I removed it from the latest commit so it should work now.

Tried that and the global error is gone but now it complains about:
local ss = require('module.screens')
I got awesome 4.3 and that is running lua 5.3 and in /usr/share/lua/5.3/lgi/ that there is no 'screens' module

Check my first comment, module.screens, util.markup and util.spacer are custom files very specific to my configuration and tightly integrated with it. I could provide them but you will then need to fix 20 other things that are not in your config. I recommend you to remove those requires that fail and replace the functions used in here with something specific to your config.

Oh, forgot that
thx
