This command rings the bell on the display for window and returns an empty string. If the -displayof option is omitted, the display of the application's main window is used by default. The command uses the current bell-related settings for the display, which may be modified with programs such as xset.
This command also resets the screen saver for the screen (unless -nice is specified). Some screen savers will ignore this, but others will reset so that the screen becomes visible again.
KBK 2003-05-29: Just remember that [bell] is a Tk command, not a Tcl command, and there's no problem on Windows. (At least it works for me.)
DKF 2003-05-30: However, exactly how the "bell" sounds varies between platforms. It's not always a simple beep, and shouldn't be rung frequently. But then it shouldn't be rung frequently anyway...
Does bell require the Windows or MacOS user to have a Tk console open?
