I am on a mission to become proficient with keyboard shortcuts, and I keep cheating by accident and using my trackpad. I want to be rigorous in my attempt to learn, so how do you toggle the trackpad on and off?
I found information on how to turn it off if you use a mouse, but that defeats the purpose of what I am trying to do.
In the spirit of learning keyboard shortcuts, if anyone knows how to set a keyboard shortcut to toggle the trackpad, that would be optimal.
To turn off the track pad you’ll need to attach a mouse or wireless trackpad but you don’t need to use it.
To turn off the trackpad when a mouse is connected:
From the Apple menu go to System Preferences
Click Accessibility
Select Mouse and Trackpad on the left
Select “Ignore built-in trackpad when mouse or wireless trackpad is present”
Actually, it is possible to disable the trackpad without needing to connect a mouse or wireless trackpad by using the Mouse Keys feature, but this will block your ability to enter text while it’s on. Mouse Keys allows you to use certain keyboard keys to control the movement of the cursor. While this answers your question, it won't allow you to do what you need.
This can be accessed in System Preferences / Accessibility / Pointer Control (or Mouse & Trackpad on older OSs) / Alternate Control Methods, and then check Enable Mouse Keys after you’ve enabled the 2 checkboxes in the Options window:
The first setting will allow this key command to turn the feature on/off so you can quickly access the trackpad again when needed.
This Apple support article explains how to use the feature and includes other ways to disable/enable it: https://support.apple.com/guide/mac-help/control-the-pointer-using-mouse-keys-mh27469/10.15/mac/10.15
