Entering your own data

Entering your own data is not very difficult. The field that is currently active for data entry is highlighted in red. This is intended to make it quicker to spot when entering data.

In addition to manually selecting the current field by clicking on it with the mouse, the program also supports the use of several keys to aid in navigation, they are: [Tab], [Shift][Tab] and [Enter]. The [Tab] key, or [Enter] key moves to the next data field, while the [Shift][Tab] key moves back one data field..

The program has a set tab order which determines the flow of data entry.

The following screens illustrate this order

Remember the current data entry field is highlighted in red.

1) Title


2) Increment


3) Tolerance


4) Isotope Labels (processed from left to right)


5) Mixture isotopic values (processed from left to right)


6) Source labels (processed from top to bottom)


7) Source isotopic data (processed one column at a time, starting at the top and going to the bottom).
