I'm writing a program that does text manipulations and want to have the
ability to highlight blocks of text for copying, deletion, etc.  It will
run under 2.0 (I'm using SAS C 5.10 on a 3000).  Since the console.device
now can highlight text for its own purposes, I want to ask:
 1) Can my program use this highlighting to its own ends (e.g. the console
    hightlights a block of text for the user, but when the user presses
    BACKSPACE, the program takes over and deletes the block of text)?  I'd
    really like to not have to reinvent the wheel here.
 2) If not, what am I suppossed to do about separating my own program's 
    highlighting from the console.device's highlighting?  I realize that I
    could simply not turn console.device highlighting on, but I'd like to
    let the user use as many 2.0 features as possible.  I'd find it hard
    to believe that the designers would essentially make 'Snap' part of
    the system, but not let it be used with a program if that program wants
    to do highlighting of its own.
BTW, I don't qualify to be an official developer of any sort, so ordering
Autodocs, etc. from Commodore is out of the question (unless they've made
the 2.0 Autodocs available to the general public...).  If the AmigaDOS
Tech notes have information on stuff like this, could someone please
re-post (or mail me) the e-mail address for getting on the mailing list
(actually, even if they don't, can someone please send me the address 
anyway :-) ).

Thanks.
