+## Configuring the Behavior of Mousekeys with 3-speed constant movement
+
+In your keymap's `config.h`, you must add the line:

+Then you can precisely define 3 different speeds for both the cursor and the mouse wheel, and also whether speed selection is momentary or tap-to-select.
+For each speed, you can specify how many milliseconds you want between reports(interval), and how far you want to it to move per report(offset).
+
+For example:
+
+```
+#define MK_3_SPEED
+#define MK_MOMENTARY_ACCEL // comment this out for tap-to-select acceleration
+// cursor speeds:
+#define MK_C_OFFSET_SLOW     1 // pixels
+#define MK_C_INTERVAL_SLOW 100 // milliseconds
+#define MK_C_OFFSET_MED      4
+#define MK_C_INTERVAL_MED   16
+#define MK_C_OFFSET_FAST    12
+#define MK_C_INTERVAL_FAST  16
+// scroll wheel speeds:
+#define MK_W_OFFSET_SLOW     1 // wheel clicks
+#define MK_W_INTERVAL_SLOW 400 // milliseconds
+#define MK_W_OFFSET_MED      1
+#define MK_W_INTERVAL_MED  200
+#define MK_W_OFFSET_FAST     1
+#define MK_W_INTERVAL_FAST 100
+```
+
+Medium values will be used as the default or unmodified speed.
+The speed at which both the cursor and scrolling move can be selected with KC_ACL0, KC_ACL1, KC_ACL2 for slow, medium, and fast. However, if you leave MK_MOMENTARY_ACCEL defined then there is no need to ever send KC_ACL1, since that will be the unmodified speed.
