[NSTextView] Shift left / Undo manager

Subject: [NSTextView] Shift left / Undo manager
From: Iceberg-Dev <email@hidden>

I am currently busy re-inventing the wheel in the form a code editor.

I support Shift Left and Shift Right.

I would like to support Undo on Shift Left.

I'm wondering how this should be done as this operation modifies both the selected range(s) and the text.

I searched the archives, the NSTextView header, documentation, looked at some source code.

I am able to support the undo operation for the text changes but the selected range(s) is/are not reverted to the correct value(s).

From what I can see, Xcode (on Tiger) does not handle the selection correctly in this case either (though the result is better than mine)


Any idea?
