A TEMES document is divided into three areas: the parameter tree, the node/path name and an embedded form. By selecting a tree node, the corresponding tree path is displayed above the embedded form, and the corresponding embedded form is shown. If a tree node is represented by a plus symbol, the node can be expanded by clicking the plus symbol or by using the right arrow key. Correspondingly, a tree node can be collapsed if it is represented by a minus symbol instead. Some tree leaves can be moved within the same level. This is done with the up and down arrow keys pressed together with the Alt key (Helpful, e. g. to swap voltage channels, or if the processing order of calculated signals should be changed). Some tree leaves can be removed by pressing the Del key (e. g. filters, CAN signals or calculated signals), and some tree leaves can be inserted as a child leave by pressing the Ins key (e. g. filters, calculated signals or signal groups).
Though the embedded forms do not display the default buttons OK and Cancel, the functionality remains available via the keyboard: The Enter key represents the OK button, whereas the Escape key represents the Cancel button. By selecting a new tree node, the made changes are accepted before displaying the new embedded form. If changes are invalid, a new tree node cannot be selected. If a field’s background is painted with red color it indicates that the made changes are invalid for this field. Then, the input needs to be corrected or to be discarded with the Escape key.
