altFont: Load a font

Hello,

I recently purchased altFont and using the
buttons that came with the DEMO stack all works fine,
using altFont to embed a font in my app.

I have been able to "SuckUp" the font in the IDE.
"SpitOut" the font from the button's custom prop. into the default 
Folder.
Now all I want to do is "Load a font" from the default Folder!
Simple enough if a clicked button presents the User with a dialog
to navigate the the font, but I don't want the User to have to do that.
Why should they.
I know where the font is sitting - its in the default Folder.
So how can I replace the code below with something triggered by the 
card script
to load the font automatically rather than the button...

--snippet of code
on mouseUp
   answer file "choose a ttf file to load"
   if it is empty then exit to top
   put the fontNames into tOldList
   put the number of lines in tOldList into tNumOfFonts

   --> ONLY COMMAND FOR LOADING
   XLOAD_FONT it
   put the result into tResult
   if tResult is not empty then
     answer warning tResult
     exit to top
   end if
--etc. etc

I did get a solution from the altFont author Chris Bohnert, but it 
lacked
enough comment for this newbie to understand how to use uFileName and
uEmbeddedFile and where to put the script...

Any guidance would be appreciated,
Thanks,
Adrian
