Action blocks will contain whatever you need them to, just as event
handler code in VB would. They can contain regular REBOL code. You
don't normally *define* functions in action blocks, but you can
certainly call them from there, and that is a common idiom.

BW> (c) Nor do such blocks usually demonstrate how to change other faces.
Basically, you reference a face with a variable and use the
get-face/set-face accessor funcs (there are also clear-face and
reset-face funcs).
view layout [
rad: radio-line "Hello World!"
b: btn "Toggle" [set-face rad not get-face rad]
]
I should point out that there is often more you need to do when it
comes to some styles, and that's one of the biggest problems with VID;
needing to know how some things work internally. You can see the
source to all styles, but it takes time and effort to understand those
things.
BW> Hope you don't mind my 2 cents at this stage.
Keep it coming. Input from people new to REBOL is vital. It reminds us
of the holes we saw when we were new, but have now forgotten about.
