It is on the TODO list but I cannot say when the feature will be added.

You might bind these two functions to a pair of keys:

define pan_left ()
{
   variable c = get_scroll_column ();
   if (c == 1)
     return;
   
   set_scroll_column (c-1);
}

define pan_right ()
{
   set_scroll_column (get_scroll_column () + 1);
}

I use the Ctrl-Left/Ctrl-Right arrow keys to invoke them:

  setkey ("pan_right", "\eOc");   % Ctrl-Right
  setkey ("pan_left", "\eOd");    % Ctrl-Left

The actual escape sequences will vary with the terminal.  The above are
appropriate for my laptop.

I hope this helps.
