## Composition of the edit pageEdit

• edit toolbar (optional)
• edit box
• edit summary box
• list of templates used
• preview (optionally either on every edit page or just after pressing "Show preview"; optionally the first item)

## Dummy edit and null editEdit

If the wikitext is not changed no edit will be recorded and the edit summary is discarded.

A dummy edit is a change in wikitext that has no effect on the rendered page, such as changing the number of newlines at some position from 0 to 1 or from 2 to 3 or conversely (changing from 1 to 2 makes a difference, see below). This allows an edit summary, and is useful for correcting a previous edit summary, or an accidental marking of a previous edit as "minor" (see below).

To refresh the cache of some item in the database a lesser kind of dummy edit, called a null edit, may be sufficient: one that does not cause any change in the wikitext, and no entry in the history, in Recent Changes, etc.: this can be done by opening the edit window and saving; a section edit is sufficient. See also A category tag in a template; caching problem.

## Minor edits Edit

When editing a page, a logged-in user has the option of flagging the edit as a "minor edit". This feature is important, because users can choose to hide minor edits in their view of the Recent Changes page, to keep the volume of edits down to a manageable level.

When to use this is somewhat a matter of personal preference. The rule of thumb is that an edit of a page that consists of spelling corrections, formatting, and minor rearranging of text should be flagged as a "minor edit". A major edit is basically something that makes the entry worth revisiting for somebody who wants to watch the article rather closely. So any "real" change, even if it is a single word, should be flagged as a "major edit".

The reason for not allowing a user who is not logged in to mark an edit as minor is that vandalism could then be marked as a minor edit, in which case it would stay unnoticed longer. This limitation is another reason to log in.

## The wiki markup Edit

In the left column of the table below, you can see what effects are possible. In the right column, you can see how those effects were achieved. In other words, to make text look like it looks in the left column, type it in the format you see in the right column.

You may want to keep this page open in a separate browser window for reference. If you want to try out things without danger of doing any harm, you can do so in the Sandbox.

### Sections, paragraphs, lists and lines Edit

Note: Single equal signs work for formatting headings, however as a convention for this wiki, do not use them.

Newline:

A single newline has no effect on the layout.

But an empty line starts a new paragraph.

(<p> disables this paragraphing until </p> or the end of the section)

(in Cologne Blue two newlines and a div tag give just one newline; in the order newline, div tag, newline, the result is two newlines)

A colon indents a line or paragraph.

A manual newline starts a new paragraph.

IF a line of plain text starts with a space THEN
it will be formatted exactly
as typed;
in a fixed-width font;
lines won't wrap;
ENDIF
this is useful for:
* pasting preformatted text;
* algorithm descriptions;
* program source code
* ASCII art;
* chemical structures;

WARNING If you make it wide, you force the whole page to be wide and hence less readable. Never start ordinary lines with spaces.

(However, in most cases a section header is more useful. The horizontal dividing line should only be used if what follows is logically part of the same section; otherwise that part would be hidden in the TOC.)

Summarizing the effect of a single newline: no effect in general, but it ends a list item or indented part; thus changing some text into a list item, or indenting it, is more cumbersome if it contains newlines, they have to be removed; see also w:Wikipedia:Don't use line breaks.

Sue is reading the video policy.
• First letter of target is automatically capitalized.
• Internally spaces are automatically represented as underscores (typing an underscore has the same effect as typing a space, but is not recommended).

Thus the link above is to http://meta.wikipedia.org/wiki/Video_policy, which is the page with the name "Video policy".

Sue is reading the video policy

Link to a section on a page, e.g.

[[List_of_cities_by_country#Morocco]].

(This is called a piped link).

Same target, different name:
User:Larry Sanger|answers
Endings are blended into the link: official positions, genes
Endings are blended
into the link: [[official position]]s, [[Wikipedia:gene|gene]]s

Automatically hide stuff in parentheses: kingdom.

Automatically hide namespace: Village pump.

The server fills in the part after the | when you save the page. Next time you open the edit box you will see the expanded piped link. A preview interprets the abbreviated form correctly, but does not expand it yet in the edit box. Press Save and again Edit, and you will see the expanded version. The same applies for the following feature.

Automatically hide stuff in parentheses:
[[kingdom (biology)|]]. 
Automatically hide namespace:
[[Wikipedia:Village pump|]].

or, with alternative text (strongly encouraged)

[[Image:Wiki.png|Star Wars Wiki]]


Web browsers render alternative text when not displaying an image -- for example, when the image isn't loaded, or in a text-only browser, or when spoken aloud.

Clicking on an uploaded image displays a description page, which you can also link directly to: Image:Wiki.png

<tr> <td> Use leading space on each line to keep newlines and multiple spaces, and get typewriter font: arrow → italics link </pre> </td> <td valign="bottom">
 arrow      &rarr;

''italics''
[[link]]

</td> </tr> <tr> <td> Use typewriter font:

arrow →

</td> <td valign="bottom">

<tt>arrow      &rarr;</tt>

<tt>''italics''</tt>
<tt>[[link]]</tt>

</td> </tr> <tr> <td> Show character references:

&rarr; </td> <td valign="bottom"> &amp;rarr;</pre> </td> </tr> <tr> <td> Commenting page source:

• Used to leave comments in a page for future editors.

</td> <td>

<!-- comment here -->

</td> </tr> </table>

## Hover boxEdit

A hover box without a link is possible: <span title="2.54 cm" style="border-bottom:1px dotted">inch</span> gives inch. With Title one can use {{title|2.54 cm|inch}}.

Combined with a link, with an independent hover box text: inch *

Since it depends on the browser whether the hover box appears, it should only be used for non-essential information, for example information one can also find by following the link.

Some browsers show the hover box only a number of seconds. Even though it reappears when the cursor is moved away and back, this makes the hover box unsuitable for long or complicated text.

Details of what the browser shows may vary, e.g. "Title:" in front, indentation, code like "</p><p>" being shown, with or without newline, etc.

## TemplatesEdit

Some part of a page may correspond in the edit box to just a reference to another page, in the form {{name}}, referring to the page "Template:name" (or if the name starts with a namespace prefix, it refers to the page with that name; if it starts with a colon it refers to the page in the main namespace with that name without the colon). This is called a template. For changing that part of the page, edit that other page. Sometimes a separate edit link is provided for this purpose. A convenient way to put such a link in a template is with a template like m:Template:ed. Note that the change also affects other pages which use the same template.

## Page protectionEdit

In a few cases the link labeled "Edit this page" is replaced by the text "Protected page" (or equivalents in the language of the project). In that case the page cannot be edited.

## Position-independent wikitextEdit

## Separating editsEdit

When moving or copying a piece of text within a page or from another page, and also making other edits, it is useful to separate these edits. This way the diff function can be usefully applied for checking these other edits.

## Error messageEdit

If, due to server problems, a save command results in an error message, either the saving has failed, or just the confirmation. Check e.g. My Contributions to find out.
