C = ctrl
S = shift
A = alt
duplicate line : C + S + d
delete line : C + d
shift line up: A + up arrow
shift line down: A + down arrow
Thanks for the suggestion! Until we get more keyboard shortcuts worked out, we do have vim and emacs modes that provide more advanced editing features.
Under the emacs mode, how can I run the command fill-paragraph; emacs [Alt + q] ?
Just to add: The keyboard shortcuts that are available are documented in the menus at the top of the editor.
Where can I find an overview of all the available editor shortcuts? It might be helpful to provide a direct help link in the menu or sth. like GitHub's [Shift+?] modal. Cheers

Are there plans for customizable user tags or shortcuts? I'm in and out of math mode all the time and have locally defined numerous commands that I really cannot do without.
