Use these options to turn on/off the top, bottom and session status lines. Note that turning on status lines does not cause information to appear on the lines, nor does it provide any additional space for normal terminal operations. Status lines are accessible only by program control, and are optionally used by programmers for, well, status information.
The session status line, added in A-Shell 1213 of April 2011, displays a session clock (how long this session has been active) and, during host-client file transfers, a progress indicator.
