“Toggle” element i. Next to this toggle is found an arrow button displaying a menu containing additional checkboxes for the following elements: em, dfn, cite.

“Toggle” element b. Next to this toggle is found an arrow button displaying a menu containing additional checkboxes for the following elements: strong, abbr.

“Toggle” element tt. Next to this toggle is found an arrow button displaying a menu containing additional checkboxes for the following elements: code, var, kdb, samp.

Displays a menu letting the user change the character case of selected text. If a single node is selected, this converts the character case of all the text contained in this node. If there is no selection of any kind, this converts the character case from caret position to end of word, then it moves the caret to the next word.

Convert implicit or explicit selection to plain text.

Converts the selection, if any, to a link; simply inserts an empty link at caret position otherwise. A link is an a element having an href attribute.

This button displays a menu having 2 entries: Set ID and List Anchors and Links.

The List Anchors and Links menu entry displays a dialog box letting the user search and select anchors (that is, any element having an ID) and links. Its Copy button copies selected ID or link target to the clipboard.

Convert a paragraph to a list item and a list item to a paragraph, the new element having a lesser nesting level than the original one. This button automatically splits lists when needed to.

This is the inverse command of "Increase nesting level". More Information below.

Convert a paragraph to a list item and a list item to a paragraph, the new element having a greater nesting level than the original one. This button automatically creates lists or merges adjacent lists when needed to.

Note that the two above buttons strictly alternate between paragraphs and list items. This means that you'll often have to click a button twice in a row. For example, in order to create a nested list, first click anywhere inside a list item and then click "Increase nesting level" twice. First click converts the list item to a plain paragraph contained in the preceding list item. Second click converts this paragraph to the first item of a new nested list.

For the two above buttons to function, any of the following conditions should be met:

When a paragraph is to be converted to a new list using this "Increase nesting level" button, there is a quick and simple way to specify the kind of list to be created: If the paragraph is empty, simply type "*", "-", "1.", "a.", "A.", "i.", "I.", optionally followed by space characters, in it. If the paragraph is not empty, type "*", "-", "1.", "a.", "A.", "i.", "I.", followed by at least one space character, at the very beginning of it. These “prefixes” are used to create respectively: ul, ul, ol, ol[lower-alpha], ol[upper-alpha], ol[lower-roman], ol[upper-roman], as if the "Change list type" button below was automatically used.

Displays a popup menu allowing to change the type of the current list.

The list must be explicitly or implicitly selected. In order to implicitly select a list, suffice to click anywhere inside it.

Displays a menu allowing to select a type of list (ul, ol, dl). The chosen list is added after node selection or after caret at a location where it is valid to do so.

Add a p element after node selection or after caret at a location where it is valid to do so.

Add a li element or a dt/dd pair after current list item. For this command to work, suffice to click anywhere inside an ul, ol or dl element.

Add an pre element after node selection or after caret at a location where it is valid to do so.

Menu entry "Normalize Whitespace" normalizes whitespace in implicitly or explicitly selected pre element. Normalizing whitespace means: expanding tab characters to a number of space characters and removing the space characters which are common to the beginning of all text lines (that is, removing the superfluous “indentation” in the pre element, if any).

Displays a menu letting the user:

(XHTML 5 only.) Displays a menu letting the user add various kinds of MathML equations after node selection or after caret at a location where it is valid to do so.

(XHTML 5 only.) This toolbar button is present only when an XHTML 5 document is opened. Displays a menu letting the user insert a media element at caret position.

Displays a menu which allows to add an h1, h2, h3, etc, element after node selection or after caret at a location where it is valid to do so.

(XHTML 5 only.) Displays a menu which allows to add a section, aside, article, header or footer element after node selection or after caret at a location where it is valid to do so.

Displays a menu which allows to add several styles of tables after node selection or after caret at a location where it is valid to do so.
