If you work on a document it would be good to have the <ESC>-key to decline all changes and stop edit mode.

If you work on a document it would be good to have <CTRL>+<ENTER>-keys or <CMD>+<ENTER>-keys to save the document.

While scrolling through the results it would be good to have the buttons to edit, delete, etc. as a sticky row so you don't have to scroll back to the top of a document if you want to edit it.
