I recommend you to use below shortcut key instead of using default minimizing shortcut key.

You will find new menu item in the menu bar also.

Restart Window(Application) which you would like to affect by the shortcut key.(No reboot requred).

Press 'Command+Shift+M' in 'Shortcut Key' textbox.

Choose 'All Application' which means this change will affect all application, put the text 'Maximize' in 'Menu Title' textbox and.

Go to System Preferences>Keyboard>Shortcuts>App Shortcut, then click.

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

(Setup is required) :Maximize the active window.

Command-Option-M :Minimize all windows of the active application to the Dock.

Command-M :Minimize the active window to the Dock.

Sorry I made a mistake about minimizing window. Other applications like Slate and Moom always use the accessiblity API. Telling the application to change the bounds of a window is faster but it doesn't work with all applications. When you tell System Events to change the position and size through the accessibility API, there is a noticeable delay between when the position and the size are changed. Set bounds of window 1 to Ĭlick (button 1 of window 1 where subrole is 'AXZoomButton') Tell application (path to frontmost application as text) Tell application 'Finder' to set b to bounds of window of desktop I have used FastScripts to assign a shortcut to this script: try

Or add a line like this to ~/.slate with Slate: bind m:cmd shift move screenOriginX screenOriginY screenSizeX screenSizeY

If you want the shortcut to always maximize a window to fill a screen, you can use for example Spectacle: Assign a shortcut for the Zoom menu item (or whatever it's called in your locale) from System Preferences:
