Two plugins to add menu entries "Open in BBEdit" and "Open in MacVim" to PathFinder's "Commands" menu. With the latest version, they don't have default shortcuts, but you can assign shortcuts under Preferences > Features -> Keyboard. I use Cmd-Ctrl-B and Cmd-Ctrl-M myself.
The plugin is based on pathfinder_open_in_textmate.
Get compiled binaries, unzip and move into ~/Library/Application Support/Path Finder/PlugIns:
Clone this repo, get the Path Finder SDK and compile yourself.
