Chemistry databases typically have a field for structure number and another field for sample number and there is a one-to-many relationship between structures and samples. When navigating a window list, the Up/Dn keys move the cursor row to row, which is equivalent to moving from sample to sample. This trigger creates a utility that skips samples and moves the cursor from the current structure number to the next.

Example

This function is deployed as a trigger linked to an up arrow action button and executes when the button is pressed. An up arrow image is included in the widget library for your button.
