Keys in the character backend multiplexer
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.
- Ctrl-a h
- Print this help 
- Ctrl-a x
- Exit emulator 
- Ctrl-a s
- Save disk data back to file (if -snapshot) 
- Ctrl-a t
- Toggle console timestamps 
- Ctrl-a b
- Send break (magic sysrq in Linux) 
- Ctrl-a c
- Rotate between the frontends connected to the multiplexer (usually this switches between the monitor and the console) 
- Ctrl-a Ctrl-a
- Send the escape character to the frontend
