I recently switched to Elementary from Ubuntu as day-today distro. But I'm not able to use alt-spacebar menu, if I want to maximize or minimize the window. It's just I hate going over arrow keys. Yeah! Long time Vimmer! Thanks.
1Not the answer you're looking for, but you could assign alt-space to 'Toggle Maximised' in SystemSettings -> Keyboard -> Windows.– elmatoDec 11, 2015 at 11:41
At the moment, I'm using it. Again, I'm accustomed to the menu. I've use it extensively for window management. Thanks though, for reply.– GaneshDec 11, 2015 at 11:46
Try disabling Alt-Spacebar as a hotkey for toggling maximized or any other entry, this should revert Alt-Space behavior to what you are accustomed to.
By default for me Alt-Spacebar was mapped to Next Keyboard Layout in Keyboard > Universal Access, by disabling this the window menu took over properly.
