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
