StackEdit is packed with many nice features, as our document numbers grow, it's hard to navigate through documents by doing "ctrl-[" or "ctrl-]" anymore. The search document is a very good tool for that, but there is no shortcut key to call that function.
The same goes with preview panel, some times you just want to be able to toggle the preview pane on and off.
So I am suggesting to allow us to assign custom shortcut keys for all available actions to the shortcut key configuration page.
