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!!
