When you start up an editor, you will see the so-called main window. For a screen dump of the main window see figure 2.1 . Except the basic drawing commands in the drawing area, all parts of the user interface can be accessed by keystrokes as well as by mouse operations. This manual assumes that you are using the mouse as much as possible. On the left edge of the main window of the diagram and tree editors there are two sets of tiled buttons containing a bitmap symbol.
Radio buttons are a set of mutually exclusive selection options.
The visual cue is a little diamond that is filled or unfilled. A check button is a non-mutually exclusive selection option. The visual cue is a little box that is filled or unfilled. When you pass the mouse pointer over a tiled button for a second or two, a one line bubble help clue is popped up giving the full name of what the tile represents. The menu bar located under the main window's title bar organizes most of the commands and features of the editors.
