Mac: Hover to Switch Window

By Xah Lee. Date: . Last updated: .

Mac has a auto-click feature: when the pointer stops moving, it automatically does a click.

This saves you lots clicks.

And is also extremely useful as a way to switch windows.

If you have Repetitive Strain Injury, turn this on.

macOS High Sierra, v 10.13.1

  1. Go to the menu 〖Apple ▸ System Preferences…〗
  2. click “Accessibility”
  3. click “Keyboard”.
  4. click tab “Accessibility Keyboard”.
  5. click checkbox “Enable Accessibility Keyboard”.
  6. Click button “Dewell Options …” to control preference.

Each time the mouse moves, a huge keyboard panel pops up.

To stop that, click on the button “Panel Editor”, and create a new panel, add just 2 buttons in it, “click” and “pause”. Make them small.

Also, make the panel not disappear. Uncheckbox the “fade panel after inactivity” in the keyboard preference.

Also, setup a “hot corner” on the screen, so that you can move mouse there and click pause to stop the auto click.


macOS Sierra, v 10.12.6

I recommend setting the “Dewell movement tolerance” to 0. When it's not 0, small pointer movement will be ignored.

You can experiment by setting it to 0 or 50. You'll see the difference.

With Trackball

The auto-click feature is especially great when using a trackball or trackpad.
