Editing Help:Link (section)

===Inserting and deleting internal links===
* When [[Wikipedia:Edit source|editing ''source'']], links are inserted or deleted simply by adding or removing pairs of square brackets enclosing the text concerned (plus handling piped links).

There are some helpful tools:
* When using the [[WP:visualEditor|visual editor]], selecting some text, then clicking the link icon above the text box (two links of a chain) will allow the link to be added, offering a selection of possible matches and the ability to pipe.
* When using the [[WP:WikEd|WikEd]] source editor, selectable from Preferences > Gadgets > Editing, there is a "Wiki link" button (typically the first button on the bottom row). When editing, if some text is [[Selection (user interface)|highlighted]], clicking the Wiki link button will enclose it in double brackets, i.e., Wikilink it. If, however, some text is highlighted that includes one or more internal links—in many cases just a single internal link with its delimiting brackets—they will be removed instead. For a single link without pipe, the Wiki link button will toggle between linking and unlinking.
