+# ~/.config/bash/keybinds.bash — readline ports of the television keys in
+# fish_user_key_bindings.fish / zsh keybinds.zsh:
+#   ctrl-o → gho (ghq-repos cable, cd)     ctrl-e → tv git-files (nvim)
+#   ctrl-p → pj (pj cable)                 down   → pj on an empty prompt
+#   ctrl-t → tv smart autocomplete (tv init bash ships no ctrl-t)
+# Keys owned by kitty.conf never reach the shell: ctrl-h/j/k/l (pass_keys.py).
+
+# bind -x runs in the shell process, so gho's cd persists — but readline keeps
+# drawing the prompt it started with. Each key is therefore a macro: \C-xN
+# stashes the typed line and runs the command, \C-m accepts the now-empty
+# line (bash prints a fresh prompt for the new cwd; nothing reaches history),
+# and \C-x0 restores the stash into the new line.
