\textbf{Daxe Editor Overview}
The LON-CAPA Daxe editor is one of the editors which may be available in your domain for editing HTML files and LON-CAPA problem files.
It provides a dynamic graphical user interface with a preview to facilitate viewing of changes to the
resulting web page.
As Daxe understands the LON-CAPA language perfectly, it will provide a list of elements that can be inserted at the
cursor position, and can check file validity in real-time.
Daxe is an alternative to the LON-CAPA ``colorful'' editor (which is the current editor by default).
Compared to the ``colorful'' editor, Daxe provides a more dynamic interface: elements can be inserted anywhere
at any time without the need for saving and reloading the document, and the display is updated immediately.
Daxe also provides a preview that is updated whenever the document is saved.
Daxe is not meant to replace the source editor (which is sometimes called ``plain text editor'',
or ``XML editor'': this text editor can still be useful to fix errors
in a document syntax, and for authors who prefer to use a simple text editor.
Note that when Daxe is used, the resulting document will always have a correct syntax,
so it is a better-suited editor for authors who are not familiar with the syntax.
