Just as you can "Fit Artboard in Window" ⌘ 0,

And "Fit All in Window" ⌥⌘ 0,

It would be nice to fit (selected) Object to Window with simple keyboard shortcut.

I know Zoom ⌘ + with "zoom to selection" turned on does this somewhat. But often I have to continue to zoom up (+) in order to get the object to fill the screen.

The question then might be, well how much should the object fill the window? I think 150% is probably a good starting point, but being able to set the zoom percentage factor would be cool too.
