Excepting a very few special cases (e.g. vim), modality is something to be avoided.  Neither is this sort of menu something Amarok trains users for: it only happens with this one of the eight context menu arrangements I was able to find in my current layout.

If, for some reason, things cannot be undone, that should be very clear up-front.  Is there a fundamental reason that move operations aren't able to be undone? On the topic of permanent deletion, though I've personally used it in the past, I question the necessity of having it in this list.  It's not available anywhere else in the interface, so its inclusion is both dangerous and without precedent.  Conversely, moving to trash can be undone quite easily.  Is this not sufficient?

This review request has nothing to do with Drag & drop or keyboard shortcuts. It is about *context menus*.

In an operating system called Windows™ (which you might have heard of), a file context menu would contain an "Open with..." item only if the Shift key was being held. I think (but 'm not sure) it would also bypass "Trash™" if the user held Shift while clicking "Delete".

@Bart "It's not an uncommon feature."
Sorry, but it really is. Can you name more than the file browser and Amarok that have context menu entries that change depending on whether a modifier key is held?  I'd be particularly interested in hearing about non-KDE applications that have this (so I also can take them to task for doing it; this is not a behaviour to emulate). Amarok isn't even consistent about applying it; hit ^o and try it in the "Play Media" window.

I _will_ acknowledge that this behaviour is present in Dolphin, but I'm afraid I have some rather pointed questions for whoever signed off on it.  Its discovery is dependent on a user opening a context menu AND having the shift key pressed before closing the menu AND noticing that the entry has changed (especially in Dolphin which, you'll note, doesn't appear to even have the tooltip!).  It completely violates the user's expectation of transparency, and does so in a way that's unlikely to happen simply because of the mental acrobatics involved in mousing and keyboarding simultaneously.
