   * When the mouse cursor is moved below the X axis and to the left of center **Step Mode QuadA** allows adjusting the QuadA currents up and down 1 step at a time using the same resolution that the mouse movements were using. ​ Left mouse button steps QuadA current down 1 step and the right mouse button steps the QuadA current up 1 step.   * When the mouse cursor is moved below the X axis and to the left of center **Step Mode QuadA** allows adjusting the QuadA currents up and down 1 step at a time using the same resolution that the mouse movements were using. ​ Left mouse button steps QuadA current down 1 step and the right mouse button steps the QuadA current up 1 step.

   * The **Save** button will save the current values of the QuadA and QuadB currents. ​ These values may be restored using the **Rest** button. ​ This is very useful when you try to improve beam tuning and find that you have only made things worse. ​ Remember to press the **Save** button before making changes to a previously good tune of the quad so you can **Rest** if you find you made things worse.   * The **Save** button will save the current values of the QuadA and QuadB currents. ​ These values may be restored using the **Rest** button. ​ This is very useful when you try to improve beam tuning and find that you have only made things worse. ​ Remember to press the **Save** button before making changes to a previously good tune of the quad so you can **Rest** if you find you made things worse.
 +  * Sometimes, when a large step in quad current is attempted too quickly, the power supply currents will start oscillating and will not respond to adjustments of the computer control. ​ If this happens, turn of the quad main power at the quad console, run the quad currents to 0 using the **Grab** function, then turn the supply back on and reset the currents.
