A basic set of formatting tools are present under some input area, allowing you to apply some simple text styles and enhance the presentation of the text fields.
A text field which can be enriched with tagged text is easy to identify: it has the Tagged Text Editor toolbar (illustrated below) located right under it.

The term 'Tagged Text' refers to the editor inserting specific formatting code instructions within the text - these small pieces of code are named Tags.
Note that this component is not a WYSIWYG editor - it will only show some code, and does not render it as it would be when seen from the NOP.
Caution: the Tagged Text Editor must be used very carefully
Since the HTML code is visible - and therefore editable as well - your text might not render as expected if some tag has been damaged or removed by mistake.
As for most simple text editors, many of the commands are quite straightforward to understand. This is certainly the case for these:
Undo / Redo: undo (or redo) the last entered changes.
Carriage Return: Inserts a line break each time you click on it, forcing a carriage return.
Bold / Italic / Underline
Simply highlight with the mouse the text you want to edit, then click on the desired button. Should you wish to apply a second style on the same text string, please make sure to only reselect the original text - excluding all tags (tags are HTML commands placed between < > brackets).
Example
- Select the text

- Click on the Bold button - you text is now surrounded by the <b> and </b> tags (marking where to start and where to end the effect)

- Select again the same text ...

- .. and this time click on the Italic button

Notice how the <i> tags are correctly nested within the <b> tags. This gives the following sequence:
<b><i>some words</i></b> which will correctly display in the viewers' browser.
An incorrect sequence, such as <b><i>some words</b></i> is likely to be wrongly rendered. The whole text will probably be set in bold, since the bold closing tag is not located where it is expected, namely after the </i> tag.
