From man less:

-# or --shift

Specifies the default number of positions to scroll horizontally in the RIGHTARROW and LEFTARROW commands. If the number specified is zero, it sets the default number of positions to one half of the screen width. Alternately, the number may be specified as a fraction of the width of the screen, starting with a decimal point: .5 is half of the screen width, .3 is three tenths of the screen width, and so on.

So you may run less -S -#.9999 if you want to scroll "almost a full page" left or right, by hitting left or right arrow key (Esc-( and Esc-) should work as well)
