Include the shortcuts Ctrl Insert to copy & Shift Insert for pasting.
Having these shortcuts will allow left handers to have a more comfortable experience. This is because left handers will be able to keep their right hand more to the right of the keyboard. For right handers Ctrl C and Ctrl V is more comfortable for right handers because there left hand is more to the right of the keyboard, than using Ctrl Insert and Shift Insert. So please consider these shortcuts for making a more comfortable experience for us left handers.
