+### config-toggle
+
+    Synopsis:  config-toggle [-h]
+
+    Opens an interactive full-screen TUI for toggling the six opinionated
+    component categories (C1–C6) and the master disable variable without
+    having to type or remember variable names. Two scope tabs allow
+    independent per-scope configuration:
+
+      Universal — persists across all sessions (set -U)
+      Session   — current shell only (set -g)
+
+    Changes apply immediately on each Space keypress. Always available
+    regardless of the __fish_config_opinionated master state.
+
+    Navigation:
+      ↑ ↓ / j k   Move cursor
+      Space        Cycle: ON → OFF → DEFAULT → ON
+      Tab          Switch scope (Universal ↔ Session)
+      q / Escape   Exit
+
+    Flags:
+      --help / -h   Show usage.
