Let us suppose we have MDX command with one hierarchy hCustomer inside 
row axis and we would like 
to have another one hProduct. Basically we would 
like to create CrossJoin of two hierarchies. 

To do that you can write it manually around hCustomer  or you can use 
intellisense for that operation
 
§          
select part of the command that will be one set inside CrossJoin function
o         
if you select from bottom 
up (from row 12 up to row 10) then your selected set will be second 
inside function and you will insert 
hProduct on first place inside 
function
o         
if you select from top 
down (from row 10 up to row 12) then your selected set will be first 
inside function and you will insert 
hProduct on second place inside 
function
§          
now start typing "cro" for crossJoin
§          
press ENTER
BOTTOM-UP                                                                                      
TOP-DOWN
            

Type "cro"

press ENTER
BOTTOM-UP                                                                                      
TOP-DOWN
