Lock Editing / Unlock Editing

Available only in the Source window, lock editing, if enabled, prevents the user from performing edits in the source until lock editing is disabled.  This option on the View menu toggles between Lock Editing (meaning that editing is currently permitted), and Unlock Editing (meaning that editing is currently not permitted).  By default, the Source window is locked - no editing is permitted.

When the Source window is locked, changes made in other windows are automatically updated in the Source window.  Once the window is unlocked, you can make changes to the source code directly. Two features -- Refresh and Reparse -- become active when the source window is unlocked (and consequently the toolbar is updated with three extra buttons, for unlocking the text, refreshing the content, and reparsing changes made by the user, as shown in Figure B).

The button on the left ('Refresh') will update the code in the Source window based on the current entries in other windows. The button on the right ('Reparse') will update the other windows to reflect changes that have been made to the source.

Expand

Available in the Element Types, Attribute Types, and Advanced windows, the Expand option is used to bring up a dialog box for editing content models in the Element Types window, attribute constraints in the Attribute Types window, and other general editing in the Advanced window (values, instructions, locations, etc.).  Expand is available when editing most cells, with the exception of a cell that contains a name (such as an element type name or an attribute name).

Zoom In / Zoom Out

Available only on the View menu in the Element Types window, the Zoom In and Zoom Out items let you zoom in and zoom out of the diagram displayed in the content model pane of the Element Types window.


Show Selected Declaration / Show Document

Available only on the View menu in the Notes window, these two options are used to change which notes are being viewed in the Notes window.  Only one of these two options can be selected at a time.  If Show Selected Declaration is selected, the notes displayed in the Notes window are specific only to the declaration the user has selected.  If Show Document is selected, the notes displayed in the Notes window are notes related to the whole document.

Refresh

Available only on the View menu in the Source window, Refresh can be used to update the Source window if changes to the DTD have been made.

Reparse

Available only on the View menu in the Source window, Refresh can be used to parse the DTD file again if changes to it have been made.
