not sure i get the question
however, if you want to call an alias from another alias, you can use the restartsearch command
call alias | restartsearch nameofthealias
then FARR will "restart" the search with "nameofthealias"
it is a way to create menus with different level :
alias 1 | restartsearch alias1
alias 2 | restartsearch alias2
alias 3 | restartsearch alias3
then :
alias1 is :
subalias 1 | restartsearch subalias1
subalias 2 | restartsearch subalias2
subalias 3 | restartsearch subalias3
you can also go back using restartsearch...
