I am using python to wrap Windows-C this week. I tried Idle again for the first time in years. Its text navigation is nasty, and caused me to go to shift editor. For example, ctrl+shift+arrows highlighting is something I do all the time and Idle's behaviour is inconsistent with Windows convention. It is hard to know how to make it mainstream from where it is. If they changed keyboard behaviour to align with Windows-convention, it may annoy parts of its existing userbase who have become accustomed to it.
