I have begun a series of publications (tutorials) on creating & using tools to access and remember keybindings, get help, etc. across multiple ‘diverse’ desktops. I hope the series is distro agnostic… it is supposed to be that way. Anyway, I will update this post with new items as I publish them on the eirenicon site.
btw. this is all part & parcel of my bspwm & hlwm journey. Best thought of as the "Road to … " starring Bob Hope & Bing Crosby.
