Win+Up arrow = maximise
Win+Down arrow = Unmaximise
These settings can all be found in Cinnamon Settings>Keyboard>Keyboard Shortcuts>Windows.
Is that what you mean?
Come to think about it, it probably isn't what you mean, but there is an unassigned shortcut in there for 'Toggle fullscreen state' - maybe have a play with that.
Edit. The minimise window shortcut doesn't work so just remap it. I used Win+PageDown.
