I am all for more intuitive HCI design but frankly, if the small speed difference either way in mousing vs typing saves you enough time to make it worth retraining your brain and fingers, you are spending way too much time in front of the puter and have already shortened your life by more than you will save by any optimal use of mousing/keyboarding!
