I just checked with another App that has semantic zoom and Ctrl+/- works.

I know ... i just said it's managed by system and something must blocking Ctrl +/- but don't know what for now.

I'm sorry, I don't understand what you are trying to say here Petr.

The Ctrl + and Ctrl - keystrokes do not work in MM8 to move between Semantic Zoom levels. They do work correctly in other Metro apps that I've tried - e.g. Microsoft's Xbox Music App.

Semantic zoom is managed by system itself.

Ctrl + Mouse scroll wheel is implemented.

According to Microsoft's UI Guidelines, Semantic Zoom should be able to be controlled by Ctrl + and Ctrl - keys. See

This does not seem to be implemented in MM8 at the moment.
