# 3.2 Environment variables

ONYX_EDITOR:
  By default, the command line editor uses emacs key bindings. Use this variable to explicitly set the key bindings to either ``emacs'' or ``vi''.
ONYXRC:
  If this variable is set to the name of a file, that file will be evaluated as part of the initialization of interactive onyx sessions. A typical setting for this would be ```~/.onyxrc`''.
