Auto Scroll Polled Files command

This command toggles the auto scroll state of all files for which polling has been activated using the File Change Polling command.  If this is selected all polled files will automatically be scrolled to display the last line each time the files are polled.  In the case of dynamically updated files, such as log files, this ensures that the latest additions to the file are always visible when the polled file is active.  This functionality is similar to the UNIX tail command.
