+#: Set this to a value larger than zero to enable a "cursor trail"
+#: animation. This is an animation that shows a "trail" following the
+#: movement of the text cursor. It makes it easy to follow large
+#: cursor jumps and makes for a cool visual effect of the cursor
+#: zooming around the screen. The actual value of this option controls
+#: when the animation is trigerred. It is a number of milliseconds.
+#: The trail animation only follows cursors that have stayed in their
+#: position for longer than the specified number of milliseconds. This
+#: prevents trails from appearing for cursors that rapidly change
+#: their positions during UI updates in complex applications. See
+#: cursor_trail_decay to control the animation speed and
+#: cursor_trail_start_threshold to control when a cursor trail is
+#: started.
+
+cursor_trail_decay 0.1 0.3
+
+#: Controls the decay times for the cursor trail effect when the
+#: cursor_trail is enabled. This option accepts two positive float
+#: values specifying the fastest and slowest decay times in seconds.
+#: The first value corresponds to the fastest decay time (minimum),
+#: and the second value corresponds to the slowest decay time
+#: (maximum). The second value must be equal to or greater than the
+#: first value. Smaller values result in a faster decay of the cursor
+#: trail. Adjust these values to control how quickly the cursor trail
+#: fades away.
+
+cursor_trail_start_threshold 1
+
+#: Set the distance threshold for starting the cursor trail. This
+#: option accepts a positive integer value that represents the minimum
+#: number of cells the cursor must move before the trail is started.
+#: When the cursor moves less than this threshold, the trail is
+#: skipped, reducing unnecessary cursor trail animation.
