Editing WoW:User interface customization guide (section)

== Tips and tricks ==
''World of Warcraft'' supports dynamically '''reloading the user interface'''. At any time, you can modify the XML and Lua files and then reload them by typing any of the following slash-commands in the chat edit box:

* <code>/console reloadui</code>
* <code>/script ReloadUI()</code>
Some (developer-) addons also register their own commands to reload the ui, they are usually short and so more convenient for development. Just try them out to see if they are available.
* <code>/rl</code> (from Ace-Console)
* <code>/rld</code> 
* <code>/reloadui</code> 


If you are not sure what is happening in a script, '''use the [[API print|print()]] function to print a message into the default chat frame'''. This function is extremely forgiving and will print any variable.

Feel free to experiment. If you break something, starting fresh is really easy. If you have questions, look on the forums to see if other people have already figured out the answers. Occasionally, Blizzard staff will be available to answer scripting questions — we value your feedback!
