Shortcut for emphasis

Feature Requests
1

Emphasis is a very useful feature, but every time I need to popup menu and select “emphasis”.

I was wondering is it possible to add shortcut, like Command+B, to emphasis selection.

Thanks.

Command+I for italics too, please, whenever this bug gets fixed.

I found the latest MarginNote3 (v3.6.7) already support CMD+B to emphasis selection, so please ignore this feature request.
