Hello
If you don’t want a new icon like clipman of whatever in your bar there is another app called greenclip, used with rofi with a keybinding of your choice.
You can even search in the clipboard just by typing in the menu.
For that, install rofi-greenclip
And in your i3 config, just add:
exec_always --no-startup-id greenclip daemon
bindsym $mod+s exec rofi -modi “clipboard:greenclip print” -show clipboard -run-command ‘{cmd}’
Reload i3 and you can now press mod+s to retrieve all things you have copied
