add left right mouse wheel

add left right mouse wheel

I recently added actions 66 67 wheel left right to tmux

tmux/tmux#4832

because I need it to navigate graphics in apps like les and less that don't have full mouse wheel support

even less don't support actions 66 67 wheel left right only 64 65 up down

unset LESS
cat weather|less --mouse --wheel-lines=3

I am essentially adding wheel left right to all apps except emacs and vim that already had it for ages

I use touch screen

I use a touch terminal unlike most which is probably why I am doing all these patches

I don't use an actual mouse only touch screen

todo add -# flag to les

I primarily wanted it in les that is fast and snappy but no wheel support

but I noticed it needs a new option to equalise scroll speed in both directions

this works well

unset LESS
cat weather|less -S -#2

this is ridiculous fast horizontal scroll

cat weather|les -w

I will add the same option to solve this

cat weather|les -w -#2
