I understand. I'm not using sway and urxvt as someone more skilled would do. I've Made this config some years ago to try but nowadays I'm not doing computer things anymore but I've kept this config because it's light, fast and it's simply working. So basically, today I'm just copying my passwords from pass in urxvt to my webmail in Firefox with my mouse for checking mail ...
I never realized that was why people used the primaey clipboard on Linux...
But I'll be frank : fuck that. I'd rather disable it entirely and stop having to deal with random text pasting in bad places when I'm using the touchpad
