Example: To get the authenticated version of the current topic you can write %SCRIPTURL{"viewauth"}%/%WEB%/%TOPIC% which expands to https://wiki.iac.ethz.ch/bin/viewauth/System/VarSCRIPTURL
In most cases you should use %SCRIPTURLPATH{"script"}% instead, as it works with URL rewriting much better
The edit script should always be used in conjunction with ?t=%GMTIME{"$epoch"}% to ensure pages about to be edited are not cached in the browser
