Thanks for the heads up. That is quite convenient, unfortunately I'm now using vimium. I'm reminded that in my vimperator days gmail wasn't a problem because the vi key bindings just worked everywhere. All this is moot considering I can just patch the plugins. I assume vimium either has a similar capability or that it can easily be added, but it does allow a web app to trap key strokes before by default (opposite of vimperator)
