The event loop used `read -k 1`, but `-k` is not a valid fish read option (it errors with "unknown option", status 2). read therefore returned instantly every iteration without consuming a keypress, so the loop redrew the panel as fast as the terminal could render and ignored all input. The nchars flag is `-n`, not `-k`. Switch to `read -s -n 1` (one char, silent so keystrokes don't garble the panel) and add `or break` so a read failure (EOF / non-tty stdin) exits cleanly instead of spinning. Applies to the primary read and both escape sequence continuation reads.

# 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
|
||
#
