I don't know if theres anything built in, but its relatively easy to add a 
keybinding to do it yourself.

To let C-space select both start and end of selection plus cancel it, put 
the following lines into your .snd-ls file:

(bind-key (char->integer #\ ) 4
 	  (let ((selstart #f))
 	    (lambda ()
 	      (let ((set-selstart! (lambda ()
 				     (report-in-minibuffer (format #f "Selection start at ~A" (cursor)))
 				     (set! selstart (cursor)))))
 		(if (c-selection?)
 		    (begin
 		      (set! (selection-member? #t) #f)
 		      (set-selstart!))
 		    (if selstart
 			(begin
 			  (c-set-selection! (c-selected-sound) 0 (min selstart (cursor)) (max selstart (cursor)))
 			  (report-in-minibuffer "")
 			  (set! selstart #f))
 			(set-selstart!)))))))
(load-from-path "snd_conffile.scm")

I'm sure it would be possible to customize snd to become more like 
vim.
