//! Shared keyboard and interaction copy for list modals and command menus.
//!
//! One source of truth so footer hints cannot drift across surfaces. Pair
//! these with `design::list` row kinds: nested views use [`BACK`], top-level
//! pickers use [`CANCEL`], filter-aware lists append [`FILTER`].

/// Move selection.
pub const NAVIGATE: &str = "↑↓ select";
/// Commit the highlighted row.

/// Change a setting value without cycling the row.
pub const ADJUST: &str = "←→ value";
/// Type-to-filter affordance (when the list has a search field).
pub const FILTER: &str = "type to filter";
/// Nested view: leave this level (root Esc closes).
pub const BACK: &str = "Esc back";
/// Top-level picker: dismiss (after clearing a non-empty filter).
pub const CANCEL: &str = "Esc cancel";
/// Vim-style movement used by standalone ratatui pickers.
