Suggestion: make it read the sprint/crouch buttons instead of CTRL directly for air select/cancel select, respectively.

This is still a problem in 2022

You also have problems if you swap your mouse buttons with breaking blocks when creating the schematics. Maybe put all the button in controls to be rebound, like every other mod?
