Brilliant. Mind sharing them, and how you tied them to Quicksilver? That'll do me fine for now!
You have to create two separate AppleScripts to execute tiomo's functions. In the following examples 'change-brightness.sh' script is stored in Scripts folder but you can save it in any folder you want, just adjust the folder paths accordingly.
First script is to increase the brightness:
do shell script "/Library/Scripts/change-brightness.sh set + 25" password "..." with administrator privileges
Second script is to decrease the brightness:
do shell script "/Library/Scripts/change-brightness.sh set - 25" password "..." with administrator privileges
NOTE:
"..." must be changed to your user password
After you have created the mentioned AppleScripts, store them e.g. in the same folder what you used earlier for the 'change-brightness.sh'.
In QuickSilver application you can then assign keyboard shortcuts for your AppleScripts by using Custom Triggers -functionality.
Hopefully this helps.
