.. code::

	'virtualedit' 've'	string	(default "")
				global or local to window global-local
		A comma-separated list of these words:
		    block	Allow virtual editing in Visual block mode.
		    insert	Allow virtual editing in Insert mode.
		    all		Allow virtual editing in all modes.
		    onemore	Allow the cursor to move just past the end of the line
		    none	When used as the local value, do not allow virtual
				editing even when the global value is set.  When used
				as the global value, "none" is the same as "".
		    NONE	Alternative spelling of "none".
		
		Virtual editing means that the cursor can be positioned where there is
		no actual character.  This can be halfway into a tab or beyond the end
		of the line.  Useful for selecting a rectangle in Visual mode and
		editing a table.
