Commands Need Context!

Commands need context!
Especially as the number of commands grows there needs to be some standard way of assigning context to a command. By context I mean that the commands that come up first on the list when you start typing should be those relevant to the webpage you are currently looking at. And some commands could be only avaliable when you are at certain sites.

For example if I just mapped a hotel in San Francisco on google maps an then type "find chinese restaurants" into Ubiquity it should look for chinese restaurants around the hotel I'm looking at now. However if I'm looking at my email and type "find april" into Ubiquity it should run a different command and bring up all my emails that are from april. In addition you could have a "find" command without context which simply searches the web with a preferred search engine.

There needs to be some way of handling multiple commands with the same name.
