Cross-platform keyboard shortcuts for the wiki

[ajainuary]

The current keyboard shortcuts don't work beyond Mac because of lack of Command Key on other platforms. We would either need to change the keyboard shortcuts all together or have platform specific key bindings (e.g. Ctrl+N on Ubuntu opens a new Chrome Window instead of creating a new page on the Wiki).

Pretty much all keyboard press events can be overriden and their default behavior can be stopped. This can be done from the key press event as follow:

disabledEventPropagation(e);
e.preventDefault();
