Use of the leading colon in links
Within the linking brackets (    ), using a colon as the first character will provide the link without doing any special namespace function. For example,  Category:Schlemiels  will provide a link to the Category:Schlemiels page without placing the page on which the link occurs into that category.  Image:PhotoOfASchlemiel.jpg  will provide a link to the specified image page without placing the actual image on the page where the link occurs.
