Selecting graph elements from the keyboard

The SelectionKeyInteractor interactor allows both single and multiple selection of graph elements from the keyboard.
The following table lists the keyboard keys and key combinations that the SelectionKeyInteractor assigns by default to graph element selection actions:
Action Description Default key or key combination
clearSelection Clears the current selection and the currently focused graph element. Esc
singleSelect Clears the current selection and selects the currently focused graph element. If there is no element in focus, the existing selection, if any, is not cleared. Spacebar
multiSelect Adds the currently focused graph element to the current selection. However, if the element is already in the current selection, this action removes the element from the selection. Ctrl+Spacebar
selectAll Selects all graph elements. Ctrl+A
