Here's a training video (https://www.youtube.com/watch?v=enJBk8TKV9Q https://www.youtube.com/watch?v=enJBk8TKV9Q) for creating CICS Screens, which are the type of thing I think the poster was referencing. My first job was writing CICS CoBOL. There was a steep learning curve, like vim, but the users would remember the transaction/workflow codes, usually 4 character abbreviations, which would be keyed somewhere on the screen, the map/form would open and they user would tab and cursor until they press some form of submit, then then next screen in the workflow would open. The users would learn which codes took them to the screen they needed and became very fast. These were all text screens, normally 3270, with no mouse. And most often had excellent mechanical keyboards.
