Change Pointer Control settings for accessibility on Mac
On your Mac, use Pointer Control settings to make your mouse and trackpad easier to use, turn on Mouse Keys, perform certain mouse actions using keyboard shortcuts, assistive switches, or facial expressions, or to move the pointer using head pointer. The options available depend on the Mac you’re using.
To change these settings, choose Apple menu > System Settings, click Accessibility in the sidebar, then click Pointer Control on the right. (You may need to scroll down.)

Mouse & Trackpad
Adjust the mouse or trackpad’s reaction time when you double-click an item.
When dragging and dropping, drag an item to a folder and hold to open the folder.
With Spring-loading turned on, adjust how long after you drag an item to a folder and hold before the folder opens.
Ignore built-in trackpad when mouse or wireless trackpad is present
Disable the built-in trackpad on your Mac when you use a mouse or wireless trackpad.
If you use a non-Apple mouse, the driver software that came with your mouse may prevent this option from working as expected. For information, see the documentation for your mouse.

Use trackpad for scrolling: Turn scrolling on or off.

Scroll speed: The speed at which you scroll through documents and windows using the trackpad.
Use trackpad for dragging: Turn dragging on or off.
Dragging style: Choose an option to control dragging.

Alternate pointer actions
Perform a left-click, right-click, double-click, triple-click, or drag-and-drop action using keyboard shortcuts, assistive switches, or facial expressions (such as a smile or an open mouth).
To specify keys, switches, and facial expressions, or to see the ones currently specified, click the Info button :
Note: A left-click, right-click, double-click, or triple-click action occurs as soon as you use the specified switch. For example, if you set the switch for Left Click to the facial expression Stick Out Tongue, a left click occurs as soon as you stick out your tongue.
A drag-and-drop action requires you to use a switch twice: once to drag, then again to drop. For example, when you stick out your tongue, drag is activated; to drop, you must stick out your tongue again.
Move the pointer using the movement of your face or head as detected by the camera that’s built into or connected to your Mac. See Move the pointer using head pointer.
To customize, click the Info button :
To quickly enable or disable Mouse Keys or head pointer using the Accessibility Shortcuts panel, press Option-Command-F5 (or if your Mac or Magic Keyboard has Touch ID, quickly press Touch ID three times).
To specify which options are available in the panel (or which features are turned on or off when you triple-press Touch ID), choose Apple menu > System Settings, click Accessibility in the sidebar, then click Shortcut on the right. (You may need to scroll down.)
