Be sure to visit the Trace Modeler website for updates and UML sequence diagram resources!
The current selection is the currently selected diagram element. It is highlighted, so you can easily recognize it. Most of the operations in Trace Modeler are applied to the current selection.
Changing the current selection causes another diagram element to become selected.
With the mouse :
- LEFT-CLICK on a diagram element to select it.
- Should multiple elements overlap, each can be selected in turn by left-clicking again. Just make sure you don't click too fast or it will be interpreted as a double click on the current selection.
With the keyboard, when in diagram edit mode:
- Press TAB to select the next element on the diagram
- If there is no current selection, this will select the 'first' element
- Press SHIFT-TAB to select the previous element on the diagram
- If there is no current selection, this will select the 'last' element
Clearing the current selection means ensuring that nothing is selected, i.e. there is no current selection. Of course, this only makes sense if there actually is a current selection to begin with.
With the keyboard, when in diagram edit mode
- Press ESC to clear the current selection.
With the mouse
- LEFT-CLICK on the diagram background to clear the current selection.
