http://askubuntu.com/questions/124815/how-do-i-enable-emacs-keybindings- in-google-chrome#comment332725_233539 System Settings - Keyboard - Shortcuts tab - Windows section - Disable "Activate the window menu" Although this is only alt+space initially, disabling it removes all the alt+<key> window menu shorcuts.
