> It is not as if keyboard shortcuts were mutually exclusive with using mouse

Of course, nobody said that. The mouse is one of the best user interface devices that has been designed for computing. Just not for working with text.

Now nobody condemns you if you like to use the mouse for browsing your code. However, if I'm right in reading your comment as rather snippy (hard to tell on the internet ;-) ), you seem to be very ready to do that to everyone seeing the merit in getting more proficient with their keyboard...
