 @@@^#                      <Alt>+"H" : get HELP.
          You are getting help now (I hope it is useful).  You can scroll up  and  down
       the  Help  file using <PgUp> and <PgDn>.  Try it!  To get a list of possible key
       strokes, press <Alt>+"H", then "Q".
          NB you cannot invoke help on the <Return> key, press F1 instead.

       A general note about Cursors:
           A number of operations involve  the  positioning  of  cursors.  For example,
       <Enter>  selects  the  cursors  for  fitting.  Further <Enter> keypresses toggle
       between the "Start" cursor and the "End" cursors. Arrow keys and <Ctrl> move the
       cursors, <Esc> fixes them and continues with the program.
       Most functions save the cursor values to unique memory locations, even though
       the cursors look the same!
        Commands:
 @@@ A    A: compensates the displayed trace for series resistance, using the paramters
       set up under Transform-Compensate. If "Comp all" is set to ON, nothing happens.
 @@@ C    C: clears the display and re-draws the trace
 @@@ G    G: adds a grid to the display, independent of the scaling
 @@@ I    I: invert the contents of the buffer being displayed
 @@@ J    J:  jump forwards or backwards in the data file,  or to the end  "e"  or
       beginning "b".
 @@@ L    L:  subtract  a baseline from the data.  First two cursors appear- they
       indicate the section of data that will be used estimate the  baseline.  You  can
       move these!  Press <Esc> to continue. Now a horizontal line appears, with a box.
       Either use arrows to improve the baseline estimate,  or type in a number,  <Esc>
       to continue and subtract the baseline from the whole trace.
 @@@ M    M:  get mean, maximum and minimum between two points.  First two cursors
       appear,  to indicate the region to be analysed.  You can move them.  On pressing
       <Esc>,  the mean,  minimum and maximum values are obtained and written to a file
       (specified  under  the  Graph-Mean/min/max-  menu).  They  are  also dislayed on
       screen.
 @@@ N    N: integrate the data. First two cursors indicate the section of data to
       be integrated.  <Esc> to continue.  Next a baseline estimate is made by taking a
       mean  between  the two cursors,  which may be adjusted (see "L" above).  Lastly,
       repeated integrations are performed using successively larger reduction factors,
       until the integraton may be performed without an  out-of-range  error.  At  this
       point,  the integrated trace is displayed, along with cursors to show the limits
       of integration,  and a modified scale (in red).  The integrated trace is  stored
       in the other buffer.  Press "x" to see it and "x" to return to the data.
 @@@ P    P:  toggle  points/lines  in  the  display.  Note  that you will see no
       difference until the trace is re-drawn.
 @@@ R    R:  find transition point.  This shifts the trace in the buffer to align
       it  with  a particular point.  See the section Graph-Average-Set alignment for a
description.
 @@@ S    S: toggle scale lines across the whole screen ON/OFF
 @@@ T    T,t  :  "t"  tags the displayed trace (or untags it if it is already tagged),
       then automatically loads the next trace. "T" sets all tags to be the same as the
       displayed trace's tag.
 @@@ U    U:  toggle  update  screen  ON/OFF.   After  pressing  "U"  the  first  time,
       successive  screen  re-sizing  of  the  trace  does  not cause a screen re-draw.
       Pressing "U" a second time allows the  screen  to  be  re-drawn  with  the  next
       alteration.
 @@@ W    W:  change  current window size.  The display windows are described in detail
       in section 6.  Check the top L corner, which should say "window [0]" to indicate
       that you are using the zero'th window.  Pressing  "W"  allows  the  size  to  be
       altered.  First  you  should  see  little  corners  appear at the corners of the
       window.  These may be moved using arrows,  <Ctrl>,  <Pg up> and <Pg  dn>.  Press
       <Return> to fix them and continue.
 @@@ X    X:  exchange  data  buffer  and average buffer.  The label average appears on
       screen,  and the scale in is red when using the average buffer.  However the two
       buffers  are  entirely  interchangeable,  and  would be better termed "displayed
       buffer" and "not-displayed buffer".
 @@@ z
 @@@ Z    Z: zero rotation on all traces
          z: zero rotation on current trace (see Z, < and > below.
 @@@ <
 @@@ >    <,>:  these keys shift (rotate) the data in the  buffer  one  point  left  or
       right.  <Shift> and "<" or ">" move the data by several points- this movement is
       rapidly accelerated by multiple keystrokes.
 @@@ +    +:  causes the current trace to be averaged with the contents  of  the  other
       (average)  buffer.  The  number  averaged so far is displayed in the top line as
       "buf [n]"
 @@@ -    -: invert the trace in the displayed buffer.
 @@@^,    <Alt>+Z: clear the other (average buffer) and set the number averaged to
       zero.
