How many of you have wished that you could maximize your window size without having to drag your mouse around to the green button on the title bar. You will have to make your own keyboard shortcut for this one, since it isn’t set by default. This post aims to show you how this can be done.
Go to System Preferences -> Keyboard.
Choose the Shortcuts tab.
From the Left Pane select App Shortcuts. Click on + icon at the bottom of the right pane.
Enter Zoom into the menu title section and then click into the keyboard shortcut box to define your keyboard shortcut.
Make sure to enter the exact command of the menu title that you want to add the shortcut for.
