I would like to use FA to activate a screensaver on command (when I leave my pc) and have this screensaver password protect my pc.
Noticing in FA  under alias a cmd function that allows for the activation of the screensaver and also a function to lock pc. Can someone please tell me
a) what exactly happens when I use : lock PC | c:\windows\nircmd.exe lockws. I am a bit too scared to test it not knowing if I can unlock it again.
b) assuming that this allows me to lock my pc, how to combine this with my screensaver command and where I would have to set up the lock and unlock commands.

I understand the problem with aliases, the regular expressions feature can scare people away. On the other hand, it's the most powerful feature about it!

I wish I would understand what you are doing :(
I installed FARR two days ago and have set various alias groups mainly to find and launch files I often use. This is pretty good but I am very keen on understanding your more sophisticated tricks.  If I set up the opera search as per your screenshoot, nothing happens. Besides, I don't quite understand how and where you are inputting the search string.
If my first input is opera (to look for the alias of Opera), how and where do I enter the actual term I am looking for.
Sorry if I am not very clear.  :-[

I just downloaded FARR and at this point just play around with it. I am impressed with how fast and responsive it is and can see many ways of configuring it.
As it also seems a bit overwhelming, I am just wondering what other users feel to be the most important feature they use.
I know from other software that often features and tricks are somewhat hidden and I often discover some of the best gems only long after having used the program by reading the relevant forums. Obviously everyone has different criteria, but any comments would help me to quickly find the "goodies" that may not be so obvious when just reading the helpfile.
