The cheat sheet
Super+/ opens a read-only fuzzel list built by grepping the Hyprland config for -- kb: <combo> | <description> comments, one per real bind, so the list can't list a bind that doesn't exist or omit one that does. It has a short manual tail for fuzzel's own vim-style navigation keys (Ctrl+J/Ctrl+K to move between entries, Ctrl+H/Ctrl+L to move the cursor, Ctrl+D/Ctrl+U to page), since those come from fuzzel's own config and have no Hyprland bind to tag.
