create a document with a column of data ( e.g. col f ) 
1. enable macro recording
2. select col F
3. data | sort  ( sort by the defaults )
4. stop macro recorder
5. save recorded macro somewhere

you will get a macro ( see below ), however if undo the sorting and run the
macro you will notice that no sorting occurs :-/
