Press the Rename/Move button, topic will be renamed and links to the topic updated as requested.

Referring topics
Referring topics are found using the the %SEARCH% variable, see the template searchrenameview.tmpl. First, matching topics in the current Web are listed - matches are to topic. Next, all Webs (including the current one) are listed that match web.topic. Because %SEARCH% is used, Webs marked in WebPreferences as NOSEARCHALL will not show up in the search for refernces to the topic being changed.
Changed references are kept are as short as possible, i.e. topic is used in preference to web.topic.
Deleting a topic
Topics can be deleted by moving them to the Trash Web (this should be added to the default distribution). Note that topics from all Webs go into this, so there could be name clashes, the user is warned of this and asked to choose a new name. When TWiki support sub-webs, these could be created on demand in the Trash Web, which would avoid this name clash problem.
It is up to the administrator of a TWiki installation to clean the Trash Web periodically e.g. by archiving to tape of CDROM entries older than 6 months.
Redirection from old topic
Something like the following can be put in WebTopicViewTemplate and WebTopicNonWikiTemplate to show if a topic has moved. It does this by searching for the tag %META:TOPICMOVED{...}%.
This topic used to exist and was moved to:
Permissions
Permissions affect rename in various ways. To rename a topic you need both change and rename permissions. To alter refering topics, you need change permission. See TWikiAccessControl for information on setting up permissions.
