--
|

-- Why we also bind C-h: most terminals (anything not implementing the

-- kitty keyboard protocol) cannot disambiguate Ctrl+Backspace from
|
|
-- Ctrl+H — both legacy paths produce byte 0x08, which crossterm
|
|
-- surfaces as `Char('h') + CONTROL`. Binding C-h to the same command
|
|
-- makes the shortcut work on legacy terminals too. C-h was free
|

-- (pmacs does not use it as a help prefix); users wanting Emacs's
|
|
-- help-prefix can override.

-- dropping it (Emacs-flavored default; users who want strict-CUA

-- Undo / redo ----------------------------------------------------------------

-- the alternates remain bound so legacy or remote terminals still
