Precision Pointer

This scriptlet slows down (reduces to sensitivity) your cursor when you hold down the capslock button which gives you greater precision.

Paste the following into your autohotkey script:

preciseSensitivity := 2
RegRead, mouse_sensitivity_status, HKEY_CURRENT_USER, Control Panel\Mouse, MouseSensitivity
DllCall("SystemParametersInfo", Int,113, Int,0, UInt,preciseSensitivity, Int,2)

~capslock up::
DllCall("SystemParametersInfo", Int,113, Int,0, UInt,mouse_sensitivity_status, Int,2)
You can also increase or decrease the precise sensitivity by changing the value of "preciseSensitivity".
