Assign the script a keyboard shortcut. That way you will have to do this:
Press the keyboard shortcut
Enter the text
Press return key
When you use Quicksilver, there are two options
Option 1:
activate Quicksilver
press "." key
enter text
hit tab
bring up ical script
press return
Option 2:
you can setup a trigger like
ical.scpt >> Process text >> <blank>
That way you will directly get a Quicksilver window ready to accept text
from you and you have to press returned after entering the text.
You may decide to use the one that suits you.
