In the markdown editor, having text marked and pressing ctrl+b gives bold text but pressing ctrl+b again should toggle the bold styling off, not surround the text with further asterisks. ctrl+i for italic should of course also be toggleable.
Wasn't sure if this should be a separate request but they both are about behavior with bold/italic keyboard shortcuts:
It should be possible to, with no text selected, press ctrl+b and start writing bold text, just like in Word or similar programs.
