Make your own shortcut (example below:)

To maximize the active window (application), you must assign the operation a shortcut as follows;

System Preferences > Keyboard > Shortcuts > App Shortcut, click “+” to add shortcut key.
Choose “All Application” which means this change will affect all application, put the text “Maximize” in “Menu Title” textbox and press “Command+Shift+M” in “Shortcut Key” textbox.
Restart Window(Application) which you would like to affect by the shortcut key.(No reboot requred)
