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