A text label is a dragable text component that can be used to add custom description to the current network. A text label can be added to the current network by activating the Text Label Tool item of the Edit Menu or Edit Mode Tool Bar, and clicking somewhere in the Network Pane.
A text label is made editable by double clicking on the given label, which also visually changes the background color of the text label to white and enables a cursor within the label (see Figure 2 below). In editable state, standard shortcuts on text such as: Ctrl + a (select all) and Ctrl + x (cut selected) works on the text.
The text label is deselected by clicking anywhere outside the label. Also a text label cannot be moved while editable.
