This is a quick patch file for metaweblog. If you install the plugin (seriously, it is, in my opinion, very cool), you'll need this to run the command in TextMate.
I have gone a step further and modified the plugin by one tiny line and now I can run a search for posts by keyword using the plugin, and open them just like Fetch Post. Difference being I can open any post I've ever written and I can narrow the field down instantly... I will post the updated plugin, a patch for blogging.rb and a Search Posts command all together.
