We all remember ⌘C and ⌘V, but what about more exotic keyboard shortcuts? Recent Menu shows all recently used menu actions with their keyboard shortcuts under the menu bar icon. You can also execute them with just one click.
I don't understand what problem this solves, since apparently (from the video and description) it is still mouse-driven. If you were opening the list of recent commands with a keyboard shortcut, then it would save you from using your mouse, but if you have to use your mouse anyway, what's the benefit of using a different menu?
But the video went by REALLY quickly, and with no audio explaining anything, so perhaps I missed something that happened in a split second.
