//! The time views' own keys (their key context, `secondary` = Cmd on macOS, Ctrl elsewhere).
//! Every other key belongs to a command (`crate::commands`), bound by kitchen-shell's registry.
//!
//! Plot keys (pan, zoom, scroll, gain, play) work while a time view has focus (a click on it), so
//! typing in a text field never moves the recording.
