Does this app exist? (macro-related)

[AC Question]

I've exhausted Google Play. What I need:

1. A way to either record or script screen taps by x-y coordinate etc.
2. Assign different sequences of screen taps to different h/w buttons, i.e. Macro1 is activated by Volume+ key, Macro2 is activated by Volume- key, etc. Optionally, long-press detection would be very nice.

Can anyone tell me if this app or functionality exists for Android?

Thanks
