Capture signature without popup menu?

[gardenlevel]

Does anyone know a trick to capture a signature without the popup menu? Seems like it would be a pretty logical script step, but I can't seem to make it happen.

I've tested with FMPA12 and FMGo12, still not an option that I can find.

I'm trying this on FMP15 and can't find a way of doing it.
