    Introduction

    Visual Turing has a powerful editor for the "graph-program" that supports multiple levels of UNDO and the classical operations CUT-COPY-PASTE. Any operation you made in the editor - moving or inserting instructions or arrows -has a visual feed-back. You can multiple select the objects in the editor for moving or "clipboarding" them. Any instruction, arrow, machine etc. has a context menu and a properties dialog which allow you to quick-edit the attributes of the specified object. You can get the context-menu by clicking the right button over the desired object. For the properties, select the Properties option from the context menu or double-click the object if it is instruction or arrow. When you use the properties dialog you can fix this on the frame (a) with a nail or let it be free (b). If the dialog is fixed, the losing of the focus doesn't close it - something like in Open Motif. The dialog has instant effect on the edited object.

    All the operations for editing the graph are available on the main toolbar. You can see what does every button by when you "fly" over it with the mouse. A longer explanation of the command is shown on the status bar.

    For the ease of the editing process, you can toggle a grid - use the View/Grid menu option
