Modes

Terminal modes control global terminal behavior: alternate screen buffer, bracketed paste, mouse tracking, focus events, and auto-wrap. Mode support varies significantly across terminals — mouse tracking modes alone have four variants (X10, normal, button, any-event), and not all terminals implement focus reporting or all bracketed paste edge cases.
