The calculations you have defined are listed in order on this page.
You can select any one of the calculations in the list, and the buttons to the right of the dialog will become enabled. Double-clicking one will automatically bring up the calculation settings dialog.
To add a new calculation, press the New button. This will present the calculation settings dialog. Type the calculation you want to make, and press the Okay button. A more detailed description is here.
This brings up the settings dialog for the selected calculation, allowing you to make changes in the settings. The calculation settings dialog is described here.
This will delete the calculation. The only chance to undo this operation
if you delete an calculation by mistake is to press the Cancel button to quit
the dialog, but you will lose any other changes that you made.
This button makes a new copy of the selected calculation, but swaps the contexts from right to left, or from left to right. It swaps the output context, and attempts to swap the contexts of all the input parameters for that calculation.
The Up and Down buttons move the selected calculation in the list, so that you can arrange them in a specific order. This is important since the calculations are performed in the order that they are presented in the list. If one calculation is dependent upon the result of another calculation, this other calculation must appear earlier in the list.
