The documentation states that "This is the value that is seen in buffers that do not have their own value= s for this variable. The default value is meaningful for variables with local bindings in certain buffers." Take for instance the variable "mode-line-format". When do buffer variable= s=20 have their own values, and when do they not have them? How can one figure out what has been set or not (whether buffers have varia= ble values or not)?.
