# Microsoft XML Notepad - User Interface

Home > Overview >

The interface consists of the following components:

Menubar
  See Menus for description of each menu.
Toolbar
  The toolbar provides some shortcuts for commonly used menu commands, hover over the toolbar buttons to see a popup showing the menu command they invoke.
Address
  The current file being edited. This is also a convenient place to enter an HTTP address for editing an online XML file.
XSL Output Tab
  This tab contains a web browser rendered view of the HTML output from an associated XSLT transformation. XSLT transforms are defined by the following type of processing instruction in your XML documents:

      <?xml-stylesheet type="text/xsl" href="willy.xsl"?>

Node Values
  The view on the right shows the text value of the adjacent node in the tree view. For element nodes that have children it shows a light blue band because the text is in the child nodes.
Node Names
  The TreeView on the left shows the XML document hierarchy in a tree showing element, attribute and processing instructions names as well as standard names for comment, text, CDATA, whitespace, and significant-whitespace nodes.
Intellisense
  When you have an associated XSD schema, intellisense popups will prompt with expected node names and enumerated node values.
XSD Annotations
  When you have an associated XSD schema, the xsd:documentation associated with the current node is displayed in a tooltip popup and in the "Dynamic Help" tab.
Validation Errors
  The Error List at the bottom shows validation errors and warnings.
Status Bar
  The status bar at the bottom shows various messages indicating the state of the program.
Resizers
  You can move the resizers to change the ratio of space allocated to each of the main three panels.
