Create an instance of Preprocess.
Drag and drop from the output (righthand side) of the widget that emits the segmentation to be modified, here Text Field (Hamlet), to the input of Preprocess (lefthand side).
Double-click on the icon of Preprocess to open its interface.
In the Processing section, tick the Transform case checkbox.
Choose to lower or to upper in the drop-down menu on the right.
Click the Send button or tick the Send automatically checkbox.
A segmentation containing the modified text is then available at the output of Preprocess; to display or export it, see Cookbook: Text output.
