I have started using Quicksilver lately, and now I’m hitting Alt-Apple-Space (my shortcut to start QS) even on the Win PC at work. Very addictive.
43folders has all the coolest tricks that QS can do. And Uptionian thoughts has a good description on how to have your Del.icio.us bookmarks right there in QS.
But I couldn’t find out how to use QS to POST to Del.icio.us?
