Hi, in this folder :
...\X-Plane 11\Output\preferences
You have 3 files :
X-Plane Calibration.prf
X-Plane Joystick Settings.prf
X-Plane Keys.prf
You could try and copy them on your second computer, I have never tried it myself though.
There is no built in solution to save or export settings profiles, even if it would be really appreciated. Let's be patient :)
