To edit a state make sure you are in Selection mode.
To edit a state's properties, disable all DES components in the left pane first so that you don't accidentally
add the component.
Then select the state you wish to edit and click on the Edit button on the toolbar.
Alternatively, right-click on the state and select Edit. This will reopen
the DES State Editor dialog box.
Change the properties you wish and click OK.
To move a state to a different graphical position in the DES, disable all DES components in the left pane first. Click on the state you wish to move and drag it to a different position in the DES. This will also move the State Name Label. You can move just the State Name Label by clicking and dragging the label to a new position in the DES.
Notice when you have a state selected, the State Name Label will also be highlighted with a dotted border.
