[comp.sys.amiga] Amiga Basic questions

I have been doing a few tasks in Basic for my Ami and as a result I now
have a few "How do I..." questions.

1.  Blinking text - On the I*M PC side you can add 16 to a color value
in the COLOR statement and cause subsequent text to blink.  AmigaBasic
does not recognize this idea, so how can I make text blink selectively?

2.  Function key trapping - Again, on the I*M PC side you can use the 
ON KEY to trap specific function keys.  I cannot find any functional
equivelant on my Amy.

(NOTE - I thought that the Amiga version of the Microsoft Basic was a
superset of the MSDOS version.  If so these type functions are probably
there but I cannot recognize them.  I must admit that the manual that
is supplied does not do very much to explain a lot of the functionality
available to the Amy.  I have had to revert to the MSDOS manual several
times for clarification <Odd Twist>, and for functions unique to the Amy
I am doing a lot of guessing!)

3.  Scrolling - I want to build a text list of 30 to 40 lines that lays
beneath a 'cover' screen that has a window large enough to see only 15
lines at a time.  What do I do to make the window relocate relative to
the underlying text so it appears the text is scrolling up or down as 
the need dictates?  Sounds simple, but I cannot get a clue from the 
AmigaBasic manual.

I know many of these are fundamental questions once you know the answer,
but without the knowledge they are more like insurmountable opportunities!

Thanks for the help.
