Slide Glitch explanation

In The Land Of Pain, we can move with WQSD, but when you are using this controller, and want to do the slide you just T-bagging.
If you dont know that, we can move with another controller, the arrow keys ! But, if you want to have a chance to beat the WR you need a numeric keypad on your keyboard.
With the arrow keys for moving, you've 0 (on the numeric keypad) for crouching and right shift for running.

Also, for doing the slide glitch, you need to :
- moving forward
- running
- being in the way down

And its all, when you are doing all of that, just press "0" one time and you are sliding !
But this slide is not infinite, when you are in the bottom of the way down you are going to stop very slowly, so just press "0" again for stop the slide and running again.
