green blob shortcut

if command + m will minimize a window (the yellow blob in the top left corner of the window), is there a keyboard shortcut that is the equal to the green blob?

Doesn't look like it. If you look under the Window menu you'll see "Minimize" has the command + M shortcut, but "Zoom" has no shortcut. ("Zoom" is the green blob)

But you can easily add a shortcut for it in system preferences>Keyboard and mouse> keyboard shortcuts.

Well I searched it for and found this:

Ever since I started using OS X as my main OS (back at version 10.1), I kept wishing for a keyboard shortcut for the green button at the top left of each window.
