You can work with keyboard shortcuts to move or delete individual, multiple, or all nodes in the Workflow Canvas as necessary.
Selecting Individual Nodes
Use your mouse to click on and select individual nodes.
Selecting Multiple Nodes
Press and hold down the SHIFT button on your keyboard and then use your mouse to click on the nodes you wish to select. A red bounding box displays around the selected nodes.
Selecting All Nodes
Press CTRL + A on your keyboard to select all of the nodes in your Canvas. A red bounding box displays around the selected nodes.
This action will select even those nodes that are not in view on the Canvas. The red bounding box including all selected nodes will be observed to extend past your view on the canvas to indicate that some nodes are beyond the current view.
Select a node or several nodes and then use the arrow keys on your keyboard to move the node by 10px toward the direction you selected.
Select a node or several nodes and then use the SHIFT + arrow keys on your keyboard to move the node by 20px toward the direction you selected.
The selected nodes can be dragged/moved to different locations together, without changing how they are arranged relative to each other.
Selected nodes can also be moved to overlap with existing nodes.
Click anywhere else on the Canvas to deselect nodes.
Select a node or several nodes you wish to delete and then click DELETE or BACKSPACE on your keyboard. Alternatively, you can click on the Remove that displays when a node or several nodes are selected. You will be asked to confirm the remove operation before it is executed.
