Trying to get the PB help to show the Dir$ topic fails to bring up the topic.
Parse$ brings up the Parse topic.
I think the $ isn't being considered part of the Topic to search for.
It would also be nice if F1 on a FF_ functions would bring up the Function Library to the correct definition for the function. I miss the FF2 help.
It would also be really nice if it brought up the function library for any user defined functions in the library (not just FF_). I suspect this will be more difficult though.
