[issue5124] IDLE - pasting text doesn't delete selection

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

In modern text editors selecting text with a mouse moves text cursor, and moving the cursor by arrow keys cancels the selection (if Shift is not pressed). But in terminal emulators selecting text with a mouse doesn't move text cursor, and moving the cursor doesn't cancel the selection. This might be an initial reason for Tk behavior.

Since IDLE editor window is rather a text editor than a terminal emulator, I think 'replace' is more preferable. But I'm not so sure about IDLE shell window.

EditorWindow.text is not the only Text widget. There are many other Text and Entry widgets are created. We should change the behavior of all Text and Entry widgets globally. I'll try to write a patch.
