knife cut preferences

Can I change knife cut default from exact to mid points ? I can not find the settings in user preferences.

User Preferences / Input - search for knife


Useful tip, thanks.
I swapped those those as I found myself using the midpoints option more than the exact one.

Thanks that worked great.
I do not know what that drop down menu above with Blender listed there is for. mine has a second 3d program under Blender

So that is how knife cut
