 ### Step Trapezoid
 
 Keycode: **131**
-Arguments: <Steps to Make, int32_t> | <Entry Speed, steps/s, uint32_t> | <Acceleration Rate, steps/s/s, uint32_t> | <Acceleration Length, steps to accelerate for, uint32_t> | <Decceleration Length, steps to deccelerate after, uint32_t>
+Arguments: Steps to Make, int32_t | Entry Speed, steps/s, uint32_t | Acceleration Rate, steps/s/s, uint32_t | Acceleration Length, steps to accelerate for, uint32_t | Decceleration Length, steps to deccelerate after, uint32_t
+Returns: Steps Made, int32_t | on step completion
  - the stepper will load this block into its stepping buffer, and if the buffer is empty will execute the trapezoid. on it's completion, the stepper will reply with an acknowledgement
