;;; test-term-config--f8-in-term.el --- F8 reaches Emacs from inside a ghostel buffer -*- lexical-binding: t; -*-

;;; Commentary:
;; <f8> is a global binding (`cj/main-agenda-display', set in org-agenda-config).
;; ghostel's semi-char mode forwards every key NOT in `ghostel-keymap-exceptions'
;; to the terminal program, so a plain <f8> typed while point is in a ghostel
;; buffer would be sent to the program instead of opening the agenda.  Unlike the
;; F9 family, F8 is NOT re-bound in `ghostel-mode-map' -- it simply falls through
;; to the global map once the semi-char map stops forwarding it, so the only
;; wiring term-config.el adds is the keymap-exceptions entry plus the rebuild.
;; These tests require ghostel (so term-config's `with-eval-after-load' fires)
;; BEFORE term-config, then confirm the exception landed and the rebuilt
;; semi-char map no longer forwards <f8>.  `(require 'ghostel)' does not load the
;; native module, so this stays light.
