Pointer shape (OSC 22)
ESC ] 22 ; shape BELOSC 22 sets the mouse pointer cursor shape when hovering over the terminal window. The sequence
ESC ] 22 ; name BEL sets the pointer to a named cursor shape (e.g., pointer, crosshair, text, wait, help). Applications use this to provide visual feedback — a text cursor over editable regions, a pointer over clickable elements, or a wait cursor during processing. Supported by xterm, foot, Ghostty, and WezTerm. Shape names follow the X11 cursor font or CSS cursor keyword conventions.How this is testedpartial

OSC 22 ; pointer BEL and verify the terminal consumes the sequence (cursor position unchanged).The same probe runs against headless backends (via Termless) and real terminal apps (via a daemon launched in each terminal). This lets us distinguish parser correctness from rendering correctness.
