Why & How to mouse on the left?
Because of the number pad, keyboards are not made symmetrically. This results in the right hand reaching too far out to the side to use the mouse. This strains the neck, shoulder, and arm.
The easiest and cheapest way to deal with this is to mouse on the left. As you can see in the picture above placing the mouse on the left reduces reach.
Anything new takes a while to get accustomed to. Start slowly mousing on the left for one hour at first. As you become more comfortable with this you can increase the time until it is all day.
How to switch:
Go to Start menu. Click Settings. Click Control Panel. Click Mouse. Click the check box that says “Switch Primary and Secondary Buttons” or box that allows left mousing. Click Apply.
Now place the mouse on the left and center your bellybutton at the "B" button on the keyboard.
- Be patient as you learn. Your speed and accuracy will improve with time and it is worth it to reduce your risk of injury!
- If you absolutely do not want to do this you should consider a keyboard without a number pad or one on the left side.
