keystroke commands needed & issues with IE & Opera

I've put together the following keyboard shortcuts and they work great in Firefox and Chrome however they break IE and don't work in Opera

Secondly, I cannot find the commands for headings (h1, h2, h3, etc.) to set keystrokes/shortcuts in CKEditor, does anyone know what to use?: ?:

I've tried all the commands that I could find for headings in the ckeditor.js file but no luck

sorry, not a programmer. . . just following the info I've found in the documentation for CKEditor. Thanks.
