The Footnote FD (Field Delimiter) requires you to enter the ASCII code for a keystroke. For instance, 9 is the ASCII code for the <Tab> keystroke. Instead of looking up these ASCII codes on the internet, you can create an NPR Report that allows you to press the keys and their ASCII codes will be displayed on the screen. Here are the steps:
"_%(MIS)USER..zcus.report.M..s(0)_"
IF{'/GO 1^/GO,1^/Z.PRT.SUPPRESS.PRINTING^/R.FRAGMENT},
"Press Any Key for ASCII Code or <Esc> to Exit";
DO{E(#S^Y)^X'=@Z.esc.key P(0,0,X:10L)_P(0,15,Y:0X)^#},
@W.return("ASCII code for <Esc> is "_@Z.esc.key)
