Emacs commands are very long and descriptive. It may be a good idea to shorten commands you use frequently. This can be done by defining aliases.

Ergoemacs-mode already adds support for a few commonly used commands like allowing eb be the same as eval-buffer. These are defined in the variable ergoemacs-aliaeses which may be customized. This can also be turned off by setting ergoemacs-use-aliases to nil:

(setq ergoemacs-use-aliases nil)
