//! The bleats pane's match axis: `/` opening the box, what typing into it
//! narrows live, abandoning it restoring what the axis held, and `n`/`N`
//! stepping between matches.
//!
//! Tests only, because the code they drive is shared and lives elsewhere: `/`
//! is claimed by the dispatcher in [`super::super::feed_keys`] ahead of the
//! pane's keymap, and `n`/`N` are two arms of [`super::keys`] that step
//! through its `scroll_bleats_back`. The sheep pane's embedded feed runs the
//! same dispatcher, so carving either out of there would split a shared keymap
//! in two.
