Given that Henrique actually went through the trouble of writing this recommendation to ask for a feature that already implemented in Sublime Text 2,I'd say is that Sublime Text 2 needs some sort of 'dynamic cheat sheet'. For example, what if you could open some sort of tab, such that for every key press (or combination of key PRESSes [not release]) a set of commands that can follow that key current key press combination popped up, stating the remaining key presses and the name of the command.
