6During emulation, if you are using a character backend multiplexer
7(which is the default if you are using ``-nographic``) then several
8commands are available via an escape sequence. These key sequences all
9start with an escape character, which is Ctrl-a by default, but can be
10changed with ``-echr``. The list below assumes you're using the default.
