Would it be possible to, while in edit mode in a node (so while markdown & latex are not rendered), to press esc (or other button) to exit edit mode, therefore having the content rendered? Even better if one could go back to the same point he was in edit mode by pressing esc again.
This would be really convenient while editing nodes with plenty of markdown and latex content, to check the result of what is being written, without having to click with the mouse outside the node area to have the content rendered and then click on the node to go back to the point that was being edited.
