I have a gaming mouse I've used when filling out 1,000's of patient records quickly. I set a button for copy, a button for paste, and a button for close tab/next tab, etc.
I have the ability, therefore, to eliminate the extra steps of right clicking or closing the the tab, and I can get into a rhythm of just copying and pasting very, very quickly. I will be the fastest freelancer to do this, unless they have teams of people splitting up the work.
