How can I count keys before keybindings(Karabiner)?

I’m using Karabiner to remap keys of Mac OS X.
For example, [Ctrl + n] instead of [down key], [Ctrl + m] instead of [enter key].

However, WhatPulse doesn’t count these keys.
I want to count [Ctrl + n] not [down key].

How can I get keys before remapping from Karabiner?
