A look back: WordPerfect on DOS (2023)

An interesting thing about WordPerfect was that most of the keyboard shortcuts were built around the row of function keys at the top of the keyboard, so they were difficult to remember, compared to modern keyboard shortcuts. For this reason, nearly every WordPerfect user I knew had a little piece of plastic or laminated paper that they placed above the row of function keys that listed all of the keyboard shortcuts on it to help them remember.

The function keys were no more difficult to use than any other key shortcut. However since keyboards had that space they put the chart there and so could find the less commonly used commands. Everyone quickly learned which key was save, but there were many many others that they didn't use and so they didn't know - but if they wanted it they could look at the chart and find it.

GUIs are more discoverable (when done well), but DOS didn't really have a GUI option, so this was a second best. VI and emacs users sometimes print shortcut charts as well.

Most modern keyboard shortcuts are mnemonic such as Ctrl-S for Save, which makes them easier to remember than function keys.

Might be true for saving, but there are far too many shortcuts. What makes it easier to remember that Ctrl+X is cut and Ctrl+V is paste?

Ctrl-X for cut because scissors form an 'x' if you squint hard enough?
