I have a 5th grade math book with instructions for using a calculator. Attached is a copy of the print page. Any suggestions for doing the example and problems 1 and 2 would be appreciated. Technical guidelines suggested underlining the commands but underlining and double underlining is used in the example.
As for the calculator examples you shared, it looks like square shapes will work very nicely for the "keycharts." I am not sure what to recommend for print's empty double low line. Maybe the visible space (⠬ dots 346) with the transcriber-defined typeform you've used for the double underline applied to it?
That would have the first example keychart and the first empty keychart looking something like this:
There may be an argument to be made for using the underline tyepform with a visible space instead of the underscores.
