I assume you mean 'right arrow key' and not 'right error key'?
I have worked in many data entry systems, with thousands of users world wide. users will come up with the most amazing hacks, I remember back in the (DOS) days, I wrote a tracking system to get/put the work, on the GET part, it would pause for 30 seconds if there wasn't any work available
somehow the users figured out that if they hit enter/pause really really fast after pushing GET, the system would count down from 30 to 0 in less than a second and they would increase their chances of getting work faster since they didn't have to pause now... freaking users!!
