Keyboard shortcut to make window fill up screen

Question

Is there a keyboard shortcut or a way of setting one to fill the window to the whole screen size, without actually being full screened.

There is a way by holding shift and clicking the green plus icon, but I'd prefer a keyboard shortcut for this.

Answer 1

There's no shortcut key… & in fact Opt/Green dot doesn't always fill the entire screen; that depends on app & document type, sometimes it only fills vertically.

The way to guarantee it expands to the entire screen area is to Opt/double click any window corner [when the cursor turns to a double arrow].

You can change double click behavior on window title through System Preferences -> Dock & Menu Bar

This wouldn't solve your problem because you want a keyboard shortcut. So go to System Preferences -> Keyboard -> Shortcuts choose Applications from the list (it's the last one) you will see All Applications on right panel. Click + icon below. A form box will appear.

Application defaults to All Application. You can choose if you want the shortcut to work only on a specific application.

The Menu Title is the most important one you need to type Zoom or if you are using your mac in another language you need to type the option what's under "Window" -> "Zoom" For example I use my mac in Turkish so I need to type Büyüt/Küçült to make the shortcut work.

Lastly enter your preferred keyboard shortcut by clicking the box and pushing down the keys you want as a shortcut.

I hope it helps, this is my first answer. :)

You can check out Window Management apps on AppStore https://apps.apple.com/en/story/id1519883681?l=en

You can also try Rectangle for free or Magnet (paid app) which are both very good for organising your windows. Many options and easy to remember their key combos.
