Hotkey to Open Hotkey Edit Window and Markdown guide

Use case or problem

I am a new Obsidian user. It’s a keyboard-based system, so learning the hotkeys seems critically important for efficiency. Yet I have to shift to the mouse to open the Hotkey window and find out what hotkeys to use, or review markdown. I’d like it to be easy to quickly display and close the hotkey window, and a markdown review list, at a keystroke.

Proposed solution

Add a hotkey that opens the hotkey window, not just the settings window. Also, add a hotkey that opens a reference guide to markdown.
