+`boo ui` adds a command palette: pressing `C-a` opens a modal to
+fuzzy-find sessions or run commands (new, kill, rename, quit, ...),
+and prompts such as kill confirmation and renaming open as modals
+too. Control variants run commands directly: `C-a C-c` create,
+`C-a C-k` kill, `C-a C-r` rename, `C-a C-n`/`C-a C-p`/`C-a C-a`
+switch, `C-a C-d` quit. See `boo help ui`.
