There are four arrows in the Spin-Box tool.

TOP ARROWS: Decrease or Increase the Parameter Data-Value by the Spin-Increment.

BOTTOM ARROWS: Decrease or Increase the Spin-Increment

Example: the Cycles / Min data-value is 111.3, and the Spin-Increment is 0.1

1.Click the Top Arrowheads of the Spin-Box tool to edit the Parameter Data-Value

a)Top : Left arrowhead to decrease Cycles / Min by the Spin-Increment :

After one click: 111.3 – 0.1 = 111.2

b)Top : Right arrowhead to increase Cycles / Min by the Spin-Increment :

After one click: 111.2 + 0.1 = 111.3 again

2.Click the Bottom Arrowheads of the Spin-Box tool to edit the Spin-Increment

a)Bottom : Left arrowhead to decrease the Spin-Increment :

Click: 0.1 ÷ 10 = 0.01

b)Bottom : Right arrowhead to increase the Spin-Increment :

Click: 0.01 × 10 = 0.1

Click again: 0.1 x 10 = 1

Results: Cycle/ Min data-value is 111.3.  Spin-Increment is 1

1.Right-click with your mouse-pointer on the data-value

This shortcut-menu shows:

To make the parameter data-value = 0, or a minimum value if it cannot = 0

To make the parameter data-value equal to the nearest value that is exactly divisible by the Spin-Increment

To copy the parameter data-value to your clipboard

To paste the value from your clipboard to the parameter data-value

Example: the Cycles / Min = 111.3

Click Round

The Spin Increment = 1.

Result: Cycles / Min data-value changes from 111.3 to 111.0.

Example: No. of Steps is 100

1.Click in the data box, so that the cursor is immediately after the value (100)

2.Enter with your keyboard: +20 to show 100+20

3.Press the Enter key on your keyboard to update the value to 120
