There are four arrows in the Spin-Box tool.

TOP ARROWS: Decrease or Increase the Data-Value

BOTTOM ARROWS: Decrease or Increase the Spin-Increment

Example: the Cycles / Min data-value is 111.3

1.Click the Top Arrowheads to edit the Data-Value

a)Top : Left arrowhead to decrease Cycles / Min by the Spin-Increment(0.1) :

After one click: 111.3 – 0.1 = 111.2

b)Top : Right arrowhead to increase Cycles / Min by the Spin-Increment(0.1) :

After one click: 111.2 + 0.1 = 111.3

2.Click the Bottom Arrowheads 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

Cycle/ Min parameter is 111.3.  Spin-Increment = 1

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

The contextual menu will show.

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

To make the parameter the nearest value that is divisible by the Spin-Increment

To copy the value in the parameter-box to your clipboard

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

Example: the Cycles / Min is 111.3

1.Click Round

The data-value is now the nearest value that is divisible exactly by the Spin-Increment(1)

111.3 > 111.0)

Example: No. of Steps is 100

1.Click in the data box, so that the cursor is immediately after the No of Step 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
