How to resize little box at end of mouse cursor

I was wondering if there is anyway to resize the little selection box that is at the tip of the arrow of the cursor. I can't see any settings for it under options or anywhere. The little square box at the end of the arrow is very small and it makes it difficult to select a line unless I am zoomed in fairly close.
I couldn't see any setting under Windows mouse settings.


found it

Never mind guys. I found out how to do it.
In case anybody is interested:

(getvar "pickbox")
will get you the pickbox size you currently have

(setvar "pickbox" 10)
will resize your pickbox to 10 pixels in this example
