Scrolling and Logging Black Night maintains a scrollback buffer and a log file. By default, the scrollback buffer is enabled, and the log file is disabled, although you can change this in the "Session Settings" dialog box. Both functions save screen data whenever it: • scrolls off the terminal screen, • is erased by a 'screen clear', or • is erased by a partial screen scroll. In addition, you can save the selected text to the log file by selecting "Log Selection" from the "Session" menu, and even though there is a default setting in the "Session Settings" dialog box, you can turn the log file on and off at any time using the "Suspend Logging" and "Resume Logging" commands in the "Session" menu. Log files are always stored in the "Home Base" folder.
