I would like to be able to set my own custom keybindings since I did not come to Deepdwn from Sublime, Emacs, or Vim. 

Very strange that I can't find keystrokes for adding h1-h6 headings in this app, since that's the main thing I use keystrokes for in my current md editor. 

Hi,

Custom keybinding is something I’d like to add, but there are a couple of features that make it harder to implement.

There aren’t any shortcuts to create headings currently, that’s something I’ll try to add in the next version.

This please.For example, I want to be able to use "Ctrl + B" for making text bold in Markdown files.
