Your jQuery selector to "Remove options for Keyboard Shortcuts" on the profile pages is a bit to common, it removes every third field in the multiple form tables.
Better would be something like
$('#your-profile .form-table').first().find( 'tr:nth-child(3)' ).remove();
fix for issue #8 and add license
Thanks for this issue and solution; I have add your solution and works fine in my test.
