# ~/.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.
