Pressing the  key while the cursor is in the
last line moves the cursor to the first line.
Pressing the  key while the cursor is in the
first line moves the cursor to the last line.
Any action on a selected line is initiated by the
 key, i.e. jumping to a new menu, starting a
procedure or starting an editing session.
Editing any parameter sets the analyzer's
function check status with the following
consequences:
