Search field over a list of actions: type to filter, arrows to move the fluid hover highlight, Enter to run. Grouped rows with icons, descriptions, and shortcut caps; suggestions listed first while nothing is typed; tabs or a borderless filter bar under the field; and a dialog shell opened by a global shortcut (default ⌘K / Ctrl+K). The list needs no primitive; the dialog is the library's Dialog in either flavor.
