My best guess is that the crackberry url is not in your QS catalog.
There's a few ways you'd have it in your catalog, most typically by
having crackberry bookmarked in Safari (pretty sure it has to be
Safari, whether or not you use it to browse the web, open it once,
bookmark the crackberry site, and quit it), AND having the Safari QS
plug-in installed.
If do not already have a Safari bookmark of the site and the plug-in
installed: Try and make the bookmark, install the plug-in, restart QS,
and then make the trigger and see if that works.
If it doesn't work there's one more thing to try:
Which is to use the web search plug-in and set up
www.crackberry.com
as a "web search" (even though we're just opening the URL and not
searching).
Do this by opening QS prefs,
Go to plug-ins and install the web-search plug-in if you don't already
have it installed
Click the Catalog tab at the top of the prefs window
Select the Custom section of the Catalog in the list on the left
Click the plus button at the bottom of the window and select Web
Search List
The info inspector drawer should pop open on the right and you should
see an empty web search source list
Click the plus button at the bottom of the source list
double click in the name field of the new web search and type
"crackberry" (or whatever"
double click in the url field and type "qss-http://
www.crackberry.com" (the "qss-" is important)
click the rescan catalog button at the bottom of the prefs window
(looks like a reload web page icon in Safari)
Quit and Restart QS
Make the following trigger:
after hitting the plus button to make a new trigger in QS prefs /
triggers
type a "." in the first pane of the trigger set up to make it a text
entry field
type "crack"
tab down to the second pane and type "Find With..."
tab down to a third pane and type "crackberry" to bring up the new
"search engine" you created in your catalog
save and set up a trigger key combination.
try that out.
