Some "how to do it" questions

I'm trying to increase the speech recognition friendliness of minimum profit,
especially for Python. There are two things which are really very important.
They may not seem like it but, they do help cut down on how much you have to say
for this particular bit of functionality. these should work identically whether
or not you're using tab characters or spaces for indentation

1) indent according to the indentation rules as defined by the previous line
(the same level of indentation for ordinary lines, indent one further for
conditionals, outdent by one for block termination)
2) outdent the current line by one tab.
bonus functions
3) indent/outdent region or selected area.

Again, since this is for speech recognition, there's no need to tie the
functionality into existing keystrokes but we can start creating a separate
keystroke sequence for those of us with broken hands.

If this is something that could be accomplished with the scripting language for
mp, some pointers of how to approach the problem would be welcome.
