Shortcuts for hierarchy levels

As of now, different hierarchies can be selected via the cmd + '+/-' buttons, but I would prefer them to have different shortcuts per indentation level, such as Ctrl + '1-6'. This would enable much faster formatting, and the adaptation of the hierarchy level of choice to multiple blocks.

Again, I appreciate the cmd + '+/-' method but I would much rather have a shortcut for the Headings - way quicker and easier, IMHO.
