press x followed by c, and then release CONTROL. This will
put you back at the command prompt if you were in Emacs. If you are
in OpenWindows, this kills the Epoch process. If you modified
any files, but did not save them, you will be prompted to do so before
exiting. To exit and save all modified buffers without being
prompted, use C-u C-x C-c instead. You can also exit via
C - ( CONTROL MINUS). The respective functions keys
bindings are labeled SAVE and SAVE-MOD on F12 and
Meta-F12, will ``save the current file'' and ``save all files'',
respectively. If you have multiple Epoch screens open, you can kill
all but the last one by selecting the Quit option with the mouse.
