+    Preprocess ``WHEEL_*`` events so that while scrolling on the horizontal
+    or vertical direction, the events aren't generated for another direction
+    even when the two directions are scrolled together (default: yes).
+
+    This preprocessing can be beneficial for preventing accidentally seeking
+    while changing the volume by scrolling on a touchpad with the default
+    keybind. Due to the deadzone mechanism used, disabling the preprocessing
+    allows for diagonal scrolling (such as panning) and potentially reduces
+    input latency.
+
+    Note that disabling the preprocessing does not affect any filtering done
+    by the OS/driver before these events are delivered to mpv, if any.
