AxisAndOhs has been updated to version 1.71
This version now has RPN scripting. You can create your own scripts to trigger more complex functionality with a single button press. These scripts are using a simplified version of the legacy RPN syntax from FSX, which is well documented online. You shouldn't have any trouble finding examples and guidance.
Example: pressing the HDG button in the cockpit of the MSFS TBM would normally set your current heading as the selected heading of the autopilot. But there is no simulator event for this in the SimConnect API, so it is not accessible from outside of the sim.
This script, that you can assign to a joystick, MIDI or keyboard key in AAO, does the trick:
(A:PLANE HEADING DEGREES GYRO, Degrees) (>K:HEADING_BUG_SET)
This script and two others (for CRS1 and CRS2) are already included in AxisAndOhs to get you started.
