//! Centered popup for the bookmark list (M7 auxiliary), opened directly by `'`. Shows local
//! (lowercase a-z) and global (uppercase A-Z) under separate headings, with the selected row
//! reversed. A plain letter jumps straight to that bookmark; `↵` = jump to selection /
//! `Ctrl-e` = edit / `Ctrl-d` = delete / `'`/`q`/`Esc` = close. Follows the help popup.
