Is it possible to implement custom input bindings that take arguments? For example "crtl+g, 55" in order to go to line 55. This is analogous to the chord bindings in VS. The only way I see to do this is to make a command change some internal state. Then the following text in a command would rely on being in that state to function properly, else it would be interpreted as its own state modifying command. Even with this solution, I don't see how to implement example above.
