Command Line v.2.0

Can I ask how everyone is setting up the command lines. For instance, how to setup a google search (for more than one word in the search) via Opera? or methyl, how you have the alt-tab setup to go to the command line plug-in?

For the google search I originally had this setup:

Alias: g
Command Line: opera.exe http://www.google.com/search?q=%1
Working Directory: C:\Program Files\Opera7

That seemed to work fine until I had more than one word in the search string. I noticed in MyIE2 (because the quick searches are configurable) that it uses http://www.google.com/search?q=%s (specifically the %s). I have no idea what the %s refers to, but I notice profbobo said with the IMDB search he uses the %s. I tried it but no luck; google searches for one string: "%s", and the other strings are opened in another Opera tab as the "DNS" name.

I have just recently started trying aliases, but not sure of some practical uses like Bob Freeman has stated.

I successfully have it working with a file search program, Locate with following:

Alias: l
Command Line: locate32.exe -r
Working Directory: C:\Program Files\Locate

I am not sure how entered strings are handled besides %1 %2 %3... for 1st string field parameter, 2nd string field parameter, ...

EDIT: I do know that if I enter g "search string" it will work properly, but I was hoping to get it working without needing the quotes.

Thanks
