The selection of the text tool causes the cursor to change to a pointing hand, as shown above, and is used to create a line of text. The user moves to the location to enter the text, presses the mouse button, inserts the text, terminating it with the <Enter> or <ctrl> key. The mouse becomes inactive until the <Enter> or <ctrl> key is pressed.

The text serves as a comment or notation for the network and may be moved or modified in the same manner as any other object.
