1 Introduction to the Window Tool Kit

1.4 Using this guide interactively

• If you use the Editor, you can edit Lisp expressions within Editor buffer windows. The viewports or windows that you create can sometimes cause occlusion of the Main Buffer window that contains your interaction with Lisp; that is, new windows can overlap and cover up the Main Buffer window. If this occurs, you can use one of the following procedures to modify the appearance of the Main Buffer window:
  • Move the mouse cursor into the Main Buffer window, and click the left mouse button to select and expose the Main Buffer.

  • Move the viewport or window that you have created.

  • Reshape the viewport or window that you have created.

  • Reshape the Main Buffer window to provide additional space in which to type new expressions.

• If you use the initialized window environment, you cannot use the Editor in the window in which you type and enter Lisp expressions. However, the viewports and windows that you create appear in the separate Lisp window and do not occlude your interaction with Lisp.
