Tap a device to see how to set it up.

Windows

In Settings under Bluetooth & devices > Mouse, change “Select your primary button” to Right, and the left and right click functions swap.

Mac

In System Settings under Mouse, set “Secondary click” to the left button, which moves the right-click function over to the left button.

Why swap the buttons?

For someone who holds the mouse in their left hand, swapping the buttons makes the button under the index finger the primary click, which feels more natural.

Dedicated gaming mouse software

Some gaming mice let you fine-tune button functions even further through the manufacturer’s own software.

A more comfortable mouse for left-handed users

The default button layout can feel awkward for people who use the mouse with their left hand. Swapping the button functions with just a couple of clicks makes everyday use feel far more natural.

Frequently Asked Questions

Does swapping the buttons also reverse drag-and-drop?

Yes, once the primary click button changes, all default actions like dragging and double-clicking follow the newly assigned button.

Can I also change what the scroll wheel button does?

That is difficult with the default mouse settings, but manufacturer-specific software can let you customize every button, including the wheel click.
