Struct TerminalKeys 

pub struct TerminalKeys {
    pub enhanced: bool,
    pub ctrl_h_is_backspace: bool,
}

What this terminal does to keys. Both facts are session-scoped and known at startup; neither is a user preference.

Fields

enhanced: bool

The kitty keyboard-enhancement flags went out, so keys arrive as keys and none of the byte collisions below exist.

ctrl_h_is_backspace: bool

0x08 is being delivered as Backspace (see app::ctrl_h), so the Ctrl+H chord never arrives at all.

Implementations

impl TerminalKeys

pub const LEGACY: Self

The terminal the default keymap is held to: no protocol, so every byte collision applies.

Ctrl+H is left as a chord rather than made pessimistic here, because the rewrite is conditional on one user’s tty erase character rather than on terminals in general (see app::ctrl_h). Holding the defaults to it would demand FocusSidebar give up Ctrl+H for everyone to serve the few — which is the trade the ctrl_h setting exists to let those users make for themselves.

pub fn detected(kitty_pushed: bool, ctrl_h_is_backspace: bool) -> Self

The traits of a live session.

kitty_pushed is whether the enhancement flags went out (terminal::TerminalSession::keyboard_enhanced). It is not the whole answer: on Windows crossterm never asks the terminal — its supports_keyboard_enhancement is a hard-coded Ok(false) — yet the console API reports keys rather than bytes, so none of the collisions this module tracks exist there (see app::ctrl_h::tty_erase_char). Folding that in here, rather than at each caller, keeps the startup notice and kimun doctor agreeing on the enhanced axis for the same terminal: both derive it as cfg!(windows) || kitty_pushed.

ctrl_h_is_backspace carries no such guarantee — it is a plain pass-through, and the two callers deliberately pass different values (see the comment at the app/mod.rs call site). This constructor cannot make them agree on that axis; it only relays what each caller decides.
