ModX - Edit Web Page
ModX is a Content Management System we are trying out to extend the ways users can manage their content without knowing web programming. This application uses a WYSIWYG (What you see is what you get) editor to create and edit content that is then assigned a graphic template and a menu placement.
The most common task for a web editor will be to edit existing content. To do this, begin by logging in to the ModX Manager pages.

On the left will be a list of page groups. The list can be expanded by clicking on the "+" sign next to the folder.

Once expanded, search for the file you wish to edit. When you see it, click on the file icon, not the file name and a menu of options will appear. Click on "Edit document".

Once into edit mode, you will see in the right frame, the sections, "Document setting", "Document content", "Template Variables", and "Access permissions". Ignore the last two and most of the first. In the Document setting area, you may want to modify the name of the item that appears in the side menu. You may also want to hide the item. This would be useful for time sensitive items like registration forms. These two options are circled below.

In the document content area, You will actually manage the content on your page. The two buttons you should be aware of in this editor are the "html" button and the "help" button conveniently located next to each other on the top right of the control panel.

Clicking on the "html" button will bring up a window where you can view and edit the source code. This may be important if you are pasting from a Word file and things look strange. The "help" button will give you all the instructions you need to use this tool. Once you are done editing, click the "save" button at the top or bottom of the page and your changes will be recorded.
