C-a C-gvbell [on|off]
Sets the visual bell setting for this window. Omitting the parameter
toggles the setting. If vbell is switched on, but your terminal does
not support a visual bell, a message is displayed in
the status line when the bell character (^G) is received. Visual bell
support of a terminal is defined by the termcap variable vb (terminfo:
flash).
Per default, vbell is off, thus the audible bell is used.
