+@table @code
+@vindex ns-use-mwheel-acceleration
+@item ns-use-mwheel-acceleration
+This variable controls whether Emacs ignores the system mousewheel
+acceleration.  When nil each `click' of the mousewheel will correspond
+exactly with one mousewheel event.  When non-nil, the default, each
+`click' may correspond with more than one mousewheel event, depending
+on the user's input.
+@vindex ns-use-mwheel-momentum
+@item ns-use-mwheel-momentum
+This variable controls whether Emacs ignores the system `momentum'
+when scrolling using a trackpad.  When non-nil, the default, scrolling
+rapidly may result in the buffer continuing to scroll for a short
+while after the user has lifted their fingers off the trackpad.
+@vindex ns-mwheel-line-height
+@item ns-mwheel-line-height
+This variable controls the sensitivity of scrolling with the trackpad.
+Apple trackpads scroll by pixels, not lines, so Emacs converts the
+system's pixel values into lines.  When set to a number, this variable
+sets the number of pixels Emacs will consider as one line.  When nil
+or a non-number the default line height is used.
+Setting a lower number makes the trackpad more sensitive, and a higher
+number makes the trackpad less sensitive.
