Lissner, CEO and Co-Founder of LEAP71, stated: “We were able to extend Noyron’s physics to deal with the unique complexity of this engine type. The spike is cooled by intricate cooling channels flooded by cryogenic oxygen, whereas the outside of the chamber is cooled by the kerosene fuel. I am very encouraged by the results of this test, as virtually everything on the engine was novel and untested. It’s a great validation of our physics-driven approach to computational AI.”

...cut if off. I did and it's GREAT. took a little while to re-center my typing. I was hunting to the left for a but it's OK now. You need the right kb for this: a membrane one. I found an old compaq [160648-202] and you can fold the membrane of the num-pad under the remaining kb after you saw off the num-pad and bolt it back together.
Easy, more room for gimpish mousing and it just looks better.
