* Help text sent from SC is often controller-specific

for example, "Use the scroll wheel to change letters..."

* Help text on Fab4 often should not be shown on the window, but rather as text shown after pushing a help button

We don't handle help text (and "soft buttons") in a way that this lends itself well to platform-specific help. 

Further, the help button on Fab4 is currently a fundamentally different way to deliver content then a help textarea widget.
