 #   One may define any number of options with a "default_parameter_"
 #   prefix. Use this to define default values for g-code parameters.
 #   For example, if one were to define the macro MY_DELAY with gcode
-#   "G4 P{DELAY}" along with "default_paramter_DELAY = 50" then the
+#   "G4 P{DELAY}" along with "default_parameter_DELAY = 50" then the
 #   command "MY_DELAY" would evaluate to "G4 P50". The default is to
 #   require that all parameters used in the gcode script be present in
 #   the command invoking the macro.
