I'm using mintty and cygwin. How to can I enable the mouse wheel inside less and man?
This is supposed to work by default, but you might be falling foul of mintty issue 262, where some mouse drivers don't deliver mousewheel events to the mintty window if they see an inactive scrollbar. A workaround is to remove the scrollbar on the Window page of mintty's options. The real fix would be to convince your mouse driver not to hide mouse events.
