Pens
Mark the start and end tag up with one swipe of the mouse! Users can define their own pen sets. Control-swipe to tag multiple lines in the same way. Use rectangular selection to mark large numbers of table cells at the same time.

Pen Sequencing
Mark complex structures up: each swipe selects the next pen to use. Fast and friendly.

Autonumber
Automatically generate IDs or other numbers when tagging with pens.

Happy Tags
Tags are clearly shown, with a combination of font, colour, outlining and highlighting. Delimiter highlighting lets you quickly locate comments, references, PIs, markup declarations. Syntax errors are circled in red, with a helpful repair message displayed.

Special Cut, Copy and Paste actions
Markup-aware actions include Paste, cleaning out attributes and content and Cut to New File which is useful for breaking a large file into entities or included files. Ten special cut registers are provided.

Validate Schematron
Schematron is the secret weapon of the large publishing players for assuring quality. Express business and publishing rules.

Validate
Search the document for errors in well-formedness or validity: DTD, XML Schemas, RELAX NG, Examplotron.

Validate and List
Generate a list of all validation errors. The list can be sorted in various ways, to spot repeated or systematic errors more easily. Use the list to navigate through the document.

Preview
Send the current document to a scriptable previewer, for example through an XSLT script to HTML.

Sidebar
Element and entity name completion, and template insertion. Templates can be automatically generated from a DTD, or custom built.

Collaborate
Help and get help from your co-workers: instant messaging, annotatable screenshots, file contention warning.

Bookmark

Snapshot
Have a problem that requires resolution from the technical expert? Save and annotate a screenshot, and send that rather than having extra copies of the document floating around.
