Bug: Cmd+Shift+O maps to two different menu commands

Just wanted to inform you that the keyboard shortcut Cmd+Shift+O maps to *both* of the menu commands:

- View > Left 1:1 Right
- Format > Ordered List

So while I'm trying to use Cmd+Shift+O and Cmd+Shift+H to toggle showing and hiding the preview pane, it keeps inserting an ordered list instead. :(

I have no preference for which one should keep the shortcut... but when I'm editing a long complex Markdown document, the preview pane is constantly flashing with every keystroke which makes it unusable, so I need to hide it, but then want to quickly show it at times so keeping *some* keyboard shortcut is essential.

Thanks so much -- wonderful app!

Start by locating the View > Left 1:1 Right and Format > Ordered List menu commands and their Cmd+Shift+O shortcut assignments. Reproduce the conflict while toggling the preview pane, then verify that the shortcut belongs to only one command and no longer inserts an ordered list unexpectedly.
