In the Windows client, when the focus is on the editor, it looks like the ESC key doesn’t have a function. (It also looks like maybe a sync doesn’t happen automatically after an edit while the focus remains on the editor, although it may just wait for the next automatic sync window; Ctrl-S does force a sync right away without changing focus.) Anyway, I would like the ESC key to change the focus from the editor to the notebook list, AND to trigger a sync if a change was made to the note. (I find this use of the Escape key very handy and intuitive, so much so that I have not upgraded Evernote from version 6.10 because that was the last version that had this navigation.)
