Each command has its own Help window and help file. The on-
line help files are text (ASCII) files.
While the Help window is open, the status line is changed to
-----------------------------------------------------------------------------
<Ctrl><F3> Find, <Shift><F3> Find again, <F5> Zoom, <Pg Dn> more, <Esc> Abort
-----------------------------------------------------------------------------
In the Help window, to search for a special word, you first
press <Ctrl><F3>, then type the word you want to search, finally
press <Ctrl><F3> again. e.g. if you want to search for the word
"help", you first press <Ctrl><F3>, then type "help", finally
press <Ctrl><F3> again. The cursor will go to the word "help".
You press <Shift><F3> to repeat the last find.
The commands in the Help window are the same as that
