Emacs being Emacs it is possible to change how Emacs behaves for every key you type. Evil mode is a fantastic example of how you can emulate most of Vi within Emacs! But it's not the only game in town.

If you don't want to buy into the whole Vi and modal editing thing there are plethora of packages to have better key bindings. To name a few: god-mode, devil-mode, meow, hydra, general, spacemacs. Pick any from this and you don't have to worry about key chording anymore.
