Dominic should adjust the mouse settings through the control panel to reverse the button functions for left-handed use, which is a simple yet effective solution.
The issue that Dominic is facing with his pointing device can be resolved by making adjustments in the computer's settings. Specifically, Dominic should adjust the settings for the mouse through the control panel of his operating system. This will allow him to configure the mouse for left-handed use, reversing the button functions so that the primary click is on the right side, which is more comfortable for left-handed individuals.
Simply moving the mouse to the other side of the computer or adjusting the sensitivity won't solve the fundamental issue of button configuration. While purchasing a new computer with a touch screen could circumvent the problem with traditional mice, it's not a necessary step as the existing mouse settings can be customized for left-handed use.
