I have found two things in the Developer’s Guide that seem to be wrong or out of date.
On page 77 the section on Deck Global Key Command mentions a “Keyboard Command”. However it is not in the accompanying image nor can I find it in the module editor.
On page 42 the section on Keyboard Shortcuts does not mention that you may use meaningful text instead of a combination of keys. Also it does not explain how you actually enter keys. This may be obvious but you cannot paste in the text from elsewhere because then you just set it to “Ctrl-V”.
I have had a break from VASSAL editing for a while, and now I am coming back the dissonance seems stronger.
