Deleting actions from the workspace is possible:

• By pressing the keyboard shortcut Ctrl+Z (Undo) - the last added action will disappear, and as a consequence, its result will also disappear from all parameters in other actions

• By moving the cursor over the action and pressing the Delete key

• By clicking on the selected action and pressing the "Cut" or "Trash" button on the top panel of the interface

If you press Ctrl+Z (Undo) key combination - the last added action will disappear, therefore, its result should disappear from all parameters in other actions. If you press Ctrl+Y (Return) - the action will be returned to the scheme, all references to the result of this action should return to the other parameters of other actions.
