you can do it using one of FARR's least known tricks
create an alias that has no regular expression, BUT uses $$1 in a result launch like so:
and now you can execute that launch on any result you search for or directory you browse from within farr by typing +ALIASNAME at start (or end) of the search.
so in the example above you could type and then hit enter:
+br c:\windows\sytem32
orc:\windows\sytem32 +br
to launch the alias on that
searched for directory.
The trick works because FARR sees that you put a + in front of the alias name and there is a $$1 in the result.
TIP 1 : You can even specify multiple results in the alias. Then after you search for something (file or folder) and hit enter, you will get a menu of your results to run on the selected file/folder.
TIP 2: Remember, you have to use the +ALIASNAME form -- if you just type the ALIASNAME without a + then farr will tread it like a normal alias and won't let you continue searching for a file/folder.
TIP 3: If you don't like hitting the + you can always create a second helper alias that matches a regular expression and emulates you typing the +ALIASNAME, using the dosearch function.
