A colleague has just come into possession of a large number of IBM PC 3270 keyboards (don't ask!). These keyboards have a number of very interesting looking keys, but the one that most intrigued us is the one at the bottom right of the block illustrated here:
In the absence of knowing its purpose, we've nicknamed it the "person in a wheelchair being chased down a hill by a boulder" key. We are relatively confident, however, that this isn't its actual name.
Any PC/mainframe history buffs able to help us out?
