Introduction

Invoking the GKB-Editor

To start up the GKB-Editor, type (user:run-gkb-editor) to the lisp listener. A large window will appear containing a copyright notice and divided vertically into five parts:

• menu bar
  This is a list of pull-down (or in CLIM 1.1, pop-up) command menus. The individual commands are each described in the appropriate sections of this manual.
• status line
  This line contains several important pieces of information. From left to right, it lists the name and package of the current KB, and the type of viewer in operation (if you have just started up, this will be the Class-Instance Hierarchy Viewer). In addition, if the KB has been modified since it was last saved, this will be indicated by three asterisks at the far left.
• graphing pane
  This large pane containing the copyright notice will contain graphical output produced by the GKB-Editor. Items displayed here are sensitive to pointer clicks.
• text pane
  This small pane is for textual input and output. Warning messages from the underlying FRS will appear here, as well as feedback and instructions from GKB-Editor commands. When asked to select a frame, you may type in its name here instead of clicking in the graphing pane.
• pointer documentation line
  When the pointer passes over a sensitive item, the operations that correspond to left, middle, and right clicks are listed here. Holding down, for example, the shift key will show operations that correspond to the various mouse clicks with the shift key held down.

The first time you open a KB, you must use the Open or New command, which will pop up a dialogue, prompting you for a filename and other information about the KB. This information is saved persistently, so the next time you wish to open the same KB, you need only select its name from the list of KBs provided when you invoke the Open command. For more information, see the section on Opening a KB.
