There appears to be some issues with the way keyboard shortcuts for tagging and moving notes to notebooks operates. I'm a heavy user of the GTD process, and so have a default notebook which I use as my 'Collection Box'. From there I will use shortcut keys (cmd + ') to tag notes will start typing and them press ctrl + cmd + m to move the note to the appropriate notebook. In previous versions this functions perfectly, in this beta release however, the shortcut keys don't seem to be triggered correctly. I'll need to tab out of fields or move the mouse to fully focus on the note as opposed to being able to do it from the note list.
