# SYNOPSIS
|
||
# config-toggle [-h | --help]
|
||
#
|
||
# DESCRIPTION
|
||
# Opens an interactive full-screen TUI for toggling the six opinionated
|
||
# component categories (C1–C6) and the master disable variable without
|
||
# having to remember variable names. Two scope tabs allow independent
|
||
# per-scope configuration:
|
||
#
|
||
# Universal — persists across all sessions (set -U / set -Ue)
|
||
# Session — active for the current shell only (set -g / set -eg)
|
||
#
|
||
# Changes apply immediately on each Space keypress — no confirm step.
|
||
# Always available regardless of __fish_config_opinionated state.
|
||
#
|
||
# ARGUMENTS
|
||
# -h, --help Print usage and exit
|
||
#
|
||
# RETURNS
|
||
# 0 Exited normally (q or Escape pressed)
|
||
# 1 Unknown flag passed
|
||
#
|
||
