T22: the macOS menu bar holds the PRD's menus, each item showing its key; Quit, Select All, Bigger, Smaller, Reset Size and Minimize take Ghostty's keys, Ctrl-Shift off macOS where Ctrl with a letter types a control byte; the font's size moves for every session, unsaved; Select All runs from the first character in the history to the last, as Ghostty's; shot lists the menus and says whether the app was active at each key
