Setting it too high makes small movements difficult. * For smoother cursor movements, lower the value of `MOUSEKEY_INTERVAL`. If the refresh rate of your display is 60Hz, you could set it to `16` (1/60). As this raises the cursor speed significantly, you may want to lower `MOUSEKEY_MAX_SPEED`. * Setting `MOUSEKEY_TIME_TO_MAX` or `MOUSEKEY_WHEEL_TIME_TO_MAX` to `0` will disable acceleration for the cursor or scrolling respectively. This way you can make one of them constant while keeping the other accelerated, which is not possible in constant speed mode. +* Setting `MOUSEKEY_WHEEL_INTERVAL` too low will make scrolling too fast. Setting it too high will make scrolling too slow when the wheel key is held down. Cursor acceleration uses the same algorithm as the X Window System MouseKeysAccel feature.
