PR# 5597 Please let Alt+Left work under more circumstances

This is a constant irritant, which I think I've seen others mention on the mailing list.

If I open a class in the editor, then move down the file to a feature I'm intersted in simply by scrolling, then double-right-click some other class or feature that I'm interested in, the editor goes directly to that feature. This is great: it's one of the best things in EiffelStudio. (I wish there were a keyboard shortcut for this behaviour, similar to Visual Studio's F12; but that's a different story.)

If I then want to go back to where I came from, I hit Alt+Left. But instead of taking me back where I was, it either goes somewhere else, or goes nowhere, because EiffelStudio hasn't remembered where I came from.

Please let Alt+Left take me back where I was.

I'm using Visual Studio a lot at the moment, and one of the best things about it is the Ctrl+Minus shortcut. It would be great if EiffelStudio's Alt+Minus could be as good.
