Easy OS 3.4.7
I like to use sticky keys; when alt or ctrl or shift is clicked it stays 'stuck' for one more keypress. Many DEs have a feature for enabling this w/ options; those which don't such as LXQt/DE or WMs, I just install the command line xkbset and configure it for sticky. Easy's mouse/kb wizard doesn't offer sticky and there is no xkbset in the available repo/s.
xkbset is typically available in such as Debian and Ubuntu repo/s.
