Review RIDE User Guide Appendix A .. many of the keyboard commands are not appropriate when using RIDE. For example, DI is not supported .. the underlying Monaco editor responds to the delete key, not the DI command. Probably ought to remove all that do not appear in the preferences box.

Raised in response to #597

It might be a case of just needing a note to say that keyboard commands that aren't configurable via the RIDE (not marked with a * in the table of all keyboard shortcuts in the Appendix) cannot be included in the programmable function key definitions in their form.
