|  | 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 Ctrl-a by default, but can be | 
|  | changed with ``-echr``. The list below assumes you're using the default. | 
|  |  |
