How to make right click using only keyboard on a Mac?

I don't know any way to show a context menu for items selected with the keyboard like what the menu key does in Windows.

To assign a keyboard shortcut for performing a secondary click at the current coordinates of the pointer, you can either:

• Use a private.xml like this with Karabiner:

  <?xml version="1.0"?>
  <root>
    <item>
      <name>Right Mousebutton</name>
      <identifier>rightMouseButton</identifier>
      <autogen>__KeyToKey__ KeyCode::OPTION_R, PointingButton::RIGHT</autogen>
    </item>
  </root>
  

• Use BetterTouchTool:

  

• Use Keyboard Maestro:

  

• Download MouseTools and assign a shortcut to MouseTools -rightClick.

For difficulties using the mouse, you can turn on Mouse Keys: Located in System Preferences > Universal Access > Mouse tab.

As it states "Use the Keyboard in place of the mouse". Also several options are available to choose from that may meet your needs.

Apple's support notes for each OSX version have more information:

• OS X Mountain Lion: Control the pointer using Mouse Keys
• OS X Mavericks: Control the pointer using Mouse Keys
• OS X El Capitan: Control the pointer using Mouse Keys
• OS X Yosemite: Control the pointer using Mouse Keys

If you can't enable it in the first method, use the second method.

Method 1

Go to System Preferences > Accessibility, find Mouse & Trackpad, then enable "Mouse Keys". If you want, go to the options menu and enable "Press the Option key five times to toggle Mouse Keys".

Method 2

Press Option-Command-F5, and a window will pop up. Select "Enable Mouse Keys".

How to use Mouse Keys

To right click press Fn-Ctrl-I. Sometimes you might want to turn Mouse Keys off as some keys on your keyboard won't function properly. If you are using an external keyboard, just find the equivalent to the function key. To map keys on a Windows keyboard with a Mac, visit this guide.
