Everywhere

Everywhere is fast file search for the Mac: results appear as you type. Every result has keyboard actions: Space for Quick Look, reveal in Finder, copy the full path, or move to Trash.

Open it with Option-Space over any app. It finds files inside Mail and the Photos library, even on drives you have unplugged, and it works with Wi-Fi off. Nothing leaves your Mac.
