+//! The `ui` module is responsible for presenting information to the user and
+//! handling keypresses.
+//!
+//! In particular, the `Ui` struct
+//!
+//! - renders text, matched text and hints from the structured buffer content
+//!   to the screen,
+//! - listens for keypress events,
+//! - and returns the user selection in the form of a `Selection` struct.
+//!
+//! Via keypresses the user can
+//!
+//! - navigate the buffer (in case it is larger than the number of lines in
+//!   the terminal)
+//! - move the focus from one match to another
+//! - select one of the matches
+//! - toggle the output destination (tmux buffer or clipboard)
