In the evernote web application I was not able to find a way to hide the preview pane when in list mode, once the preview pane is there.
I have found old forum posts, where others were looking for the same and the result seems "feature not implemented".
So how do you hide the preview pane in Evernote Web when in list mode?
Or is it simply not possible? Or is there at least a keyboard shortcut?
I found a workaround which I will post as an answer, but is there a real solution? A keyboard shortcut would still be better.
