target last enemy in macro

Heyho guys,

Maby someone could tell me how /targetlastenemy works on this server?? Normally it should work for tbc, see here:

http://wowwiki.wikia.com/wiki/MACRO_targetlastenemy
and
http://wowwiki.wikia.com/wiki/Patch_2.3.0/API_changes

With "settings --> key bindings --> target previous enemy" it works, but I need to get it work in macros.

I believe the command you are looking for is

/targetlasttarget

you can use options such as

/targetlasttarget [harm]

etc.
