I use this alias for a similar action (open file in notepad).
The way I use it is I do a normal search and then add +edit to the ond of the search string.
[copy or print
1000>>>Edit>->Edit $$1 in Notepad++ | C:\Program Files\Notepad++\notepad++.exe $$1 /ICON=icons\edit.ico
This is from the docs:
Using Alias Action Keywords

A new feature with FARR version 2 is the ability to specify alias names in your search string using the + prefix (just like keyword modifiers).
When an alias name is specified in this way, anywhere on the search string, it does not effect search, but it will cause the alias results to be displayed AFTER the result file is selected, with the selected file name as argument $$1 in the alias.
In this way, you can perform a normal file/folder search and then launch a specific alias command with that file/folder as an ARGUMENT.
For example, you could create an alias named +hexedit
whose result contents are:
C:\Program Files\HexEditors\HexEdit.exe "$$1"
Now you can type in your search:
As you type mydocsearch words, FARR will let you search for files as normal.
After you choose the result, instead of launching the result file, you will be presented with
C:\Program Files\HexEditors\HexEdit.exe "SELECTEDFILE"
Which you can then launch.
You can use the same keyword for both alias names and search/scoring keyword modifiers.
