I think many people like to bang the ENTER key because, hey, I
finished a line of text man!
Even I type also bang on ENTER key, because when you type you want
to be fast, so you don't apply too much force or else you have to
time to switch to the other key quickly, resulting in very bad
synchonisation of fingers and keys.
But hey, the ENTER key is just an ENTER key, easily located, and
channling the frustration from controlling the force you apply to
the keys or the frustration from the unability to type quickly and
finish your work in the shortest time possible....
