How to get shift key locked when click once
I have a Macbook Pro and Macbook Air. On the Pro when I click the shift key once in compose mode the Shift key function stays active until I click the shift key again. (This means I don't have to keep the shift key pressed in the to capitalise a letter, etc).
Is it possible to set the shift key with the same functionality on the Mackbook Air?
