Command Popover Actions Menu for React

The Quick Actions button is the trigger, and the panel opens below it, lined up with its start edge. The panel is 400px wide, never wider than the screen, and has no padding, so the Command fills it. A visually hidden PopoverTitle names it. PopoverTrigger renders the button through render, and PopoverContent sets align="start".

Two CommandGroups: Quick Actions holds Open, Copy and Add to Favorites, and File Actions holds Download, Share and Delete. There is no separator, so the headings alone split them. Each row starts with a decorative icon: ArrowRight, Copy, Star, Download, Share or Trash.

Each hint is a CommandShortcut: Open shows ↵, Copy ⌘C, Add to Favorites ⌘D, Download ⌘⇧D, Share ⌘⇧S and Delete ⌘⌫. It's a label at the end of the row and binds nothing: listen for those keys yourself if they should run the action.

CommandEmpty in the list says "No actions found." It shows only when the search leaves nothing.

These items don't run anything yet. Pass onSelect to each CommandItem.

The arrow keys move through the items, Enter runs the highlighted one, and typing filters the list. Escape or a click outside closes the popover, and focus goes back to the button. CommandInput shows "Search actions..." until someone types. Command filters and ranks the items by their text on its own.
