As an editor, I want to be able to quickly and intuitively use the Composer to create stories. As there are a lot of fine keyboard shortcuts to use, I enjoy working mostly by keyboard. But I have to switch to my mouse to open the preview for a story - something, we do several times for every story. It would be a little, but really comfortable measure if you could provide a keyboard shortcut for the preview functionality, too.
Hi there! Thanks for submitting this. We'll keep this in mind as we continue to make improvements to Composer!
