Upgrading from 3820 breaks some of my triggers (all related to "current selection") about quicksilver

I took a look at the Current Selection proxy, and it wasn't working (on my system at least) because of the way QS gets the selection. QS invokes the "Get Current Selection (Internal)" service by generating the keystrokes it thinks are assigned to it, but currently they're hardcoded to be command+escape.
On my system, this was not the combo the service was assigned, and for whatever reason, I could not assign it the key combo of command+escape (probably because Front Row uses that combo and you can't reassign that as far as I can tell).

Again, I could be the only person with this exact problem, but I changed the keystrokes QS generates to command+option+shift+control+space and assigned the Get Current Selection (Internal) service that key combo in the Services settings in Keyboard preferences, and Current Selection works again, to a degree. Actions that work on plain text (Large Type, Find With…) work fine, but actions that don't act on input that is strictly plain text like Open URL don't seem to. I'll take a closer look at that later.

If you'd like to see if the above would make any difference on your machine, I've put a precompiled version of QS with the key combo change up at http://neurolepsy.com/Quicksilver.zip

You also might want to take a look at some of the built-in services in Keyboard preferences - Open URL is built in to Snow Leopard and works exactly like Current Selection > Open URL did in Quicksilver, and I've been using that as a replacement.

I also took a look at the Finder Selection proxy, but I haven't figured out what's wrong with it yet.

About the change you've made : I'm trying to find another way than relying on keystrokes (will try accessing the Service menu directly), which should fix this independently of the Service shortcut (mine's Cmd-Esc, you'll have to uncheck the Front Row one if you want this one).

I'm not sure about the Finder one too. Will have to take a look at the Finder plugin...

As I had to revert the change I made in my branch that changed the keystrokes QS responded to, I figured out how to reset it to responding to cmd+esc:
Open Keyboard preferences
Uncheck Front Row
Quit Keyboard preferences
Open ~/Library/Preferences/pbs.plist
Find the key com.blacktree.Quicksilver - Quicksilver/Get Current Selection (Internal)
Remove it and save the file
Open Keyboard preferences again
Check Get Current Selection (Internal) if it isn't already - the key combo should be cmd+esc

As far as I know the above is only applicable to 10.6, and will only do anything constructive if the key combo has been changed at some point, breaking the Get Current Selection action.

Proxies are fixed, and Neurolepsy's fix should do for anything else.
