Oh, I see. Rather unexpected, but I get the point.

Actually, the accel is case-insensitive. The second one simply overwrites
the first one. ML does not take the case of the given letter into account
and simply translate it into "Key Z" without holding any information about
the character case. So in both case, the generated
shortcut is Ctrl+Key_Z. This limits the number of shortcuts you can define,
even more when you considered that some common shortcuts are reserved.

That's why I'm thinking about extending that and take the case into account
to allow CTRL+SHIFT+... shortcuts.
