### 3.3 Tracking Mode ¶

In both GUIs if you click an arrow, entity, graph node, block or any other visual element on the chart, it is briefly highlighted and the corresponding text is selected in the internal editor. This is useful to quickly jump to a certain element in the chart text. The same way, when pressing F4, if the cursor is inside a chart element, the element is briefly flashed.

If you double-click the chart (try the background) you enter Tracking Mode, where you can select and highlight multiple chart elements at the same time. Visual elements are faintly outlined just by hoovering above them. When actually clicking on them (or pressing F4 when the internal editor cursor is inside them) will make them actually highlighted. Then you can move on to highight more. You can also remove highlighting from an element by clicking it again or by pressing F4 again.

If you click the chart background or press Escape, all highlighting is removed. Pressing Escape again will make you exit tracking mode. You can also enter tracking mode by pressing Ctrl+T. In the MFC GUI pressing the ‘`Tracking Mode`’ button on the Chart pane will also enter tracking mode.

Tracking mode is useful when you are discussing a chart (e.g., in a shared screen session) and you want to talk about various elements.
