keyboard layout - Why don't the Google Docs CTRL + ALT shortcuts work?

I'm currently using Google Docs, but when I try to use the keyboard shortcuts like Ctrl+Alt+M it gives µ instead.

Is Chrome (9) overruling Google Docs in some way?

How can I get these shortcuts working?

I'm using Chrome dev 9 on a Dutch Windows 7 with a US-layout keyboard

Answer

Here is Google's Official Shortcut Page for Google Doc. There you find that the current shortcut to insert comments is Ctrl + Alt + M and the old shortcut was Ctrl + M. I would have to assume that the old shortcut isn't supported. Which leads to this...

"Originally, US PC keyboards (specifically, the US 101-key PC/AT keyboards) did not have an AltGr key, it being relevant to only non-US markets; they simply had "left" and "right" Alt keys.

As those using such US keyboards increasingly needed the specific functionality of AltGr when typing non-English text, Windows began to allow it to be emulated by pressing the Alt key together with the Control key: Ctrl + Alt ≈ AltGr -- (wiki source).

Therefore, it is recommended that this combination not be used as a modifier in Windows keyboard shortcuts as, depending on the keyboard layout and configuration, someone trying to type a special character with it may accidentally trigger the shortcut, or the keypresses for the shortcut may be inadvertently interpreted as the user trying to input a special character."

US International Layout: Ctrl + Alt ≈ AltGr ... which means... AltGr + M = µ

Note: To resolve this issue switch to a pure US layout, not a US International keyboard layout. See steps below on how to switch.
