I would say you would have to create your own function that would handle
the enter key and look back at the existing code to determine a line of
code's indentation level. This is not a trivial task to complete, but I
believe all the functionality in the scripting language exists in order
to accomplish it. Now, since you are speaking of Python, indentation
cannot always be found correctly just by looking back at the code. For
instance, you will indent after an if statement, but at some point in
time the user is going to have to manually out-dent inorder to end the
if statement. Minimum Profit will have no way of knowing when the user
may wish to do that. I guess that's why you are asking about numbers 2
and 3 though.

I do not currently have this function, but I want it.

I do have an indent block function. It is not well tested, but works for
me when I have used it. It is:

/* indent selected block */
sub indent_block(d) {
    if (d.txt.mark == NULL) {
        mp.move(d, mp.move_bol);
        mp.insert_tab(d);
        return (NULL);
    }
   
    local currentY = d.txt.y;
   
    mp.set_y(d, d.txt.mark.by);
   
    while (d.txt.y <= d.txt.mark.ey) {
        mp.move(d, mp.move_bol);
        mp.insert_tab(d);
        mp.move(d, mp.move_down);
    }
   
    mp.set_y(d, currentY);
}
mp.actions['indent_block'] = indent_block;
mp.actdesc['indent_block'] = "Indent block";

Sorry I didn't have all the answers, but maybe others will chime in with
information too.
