No, this is not what you think! And yes, I would love to not have cursor positions count in undo / redo.

My problem is that I like to map redo to Ctrl-Y. But, if I change it in Tools / Settings / IDE shortcuts, it stays as Shift+ctrl+z in the Edit dropdown menu. I did an upgrade to 5.0, and just installed over the top of my previous installation. The IDE kept the setting in the Tools / Settings / IDE shortcuts as Ctrl+y, and it was also set as delete line in the editor shortcuts. I removed that one, and I tried deleting and re-adding the setting in the IDE shortcuts menu. Anyway, I am not sure what to do now. I even restarted the editor.

-r

Well, my bug has magically fixed itself. I closed the editor and tried it again several times. Finally after deleting the shortcut and adding it several times it finally stuck.
