Add more useful shortcuts

Would be great to have ability to add shortcut for several operations that are probably used a lot:

  • Move to the end of the last item of the current list. It is often needed when you want to add a new item after the current last item.
  • Delete an item in folder/document list. Currently you need to open menu.
  • Create a document. Position of the document - near the currently selected/opened one.
  • Add some short-cut for copy element by default. It is an often-used functionality, so no sense in leaving this function without a short-cut.

Probably others will add to the list, but these are the ones I think would be useful for all.

Note: some document/file shortcuts mentioned here overlap with this feature request:
