find-next-selected-snip

Returns a selected snip in the buffer.

• (send a-wx:media-pasteboard find-next-selected-snip start) -> wx:snip% object or null
      start : wx:snip% object or null

  Returns the next selected snip in the buffer, starting the search after start. If start is null, then the search starts with the first snip in the buffer (and thus returns the first selected snip, if any are selected). If no more selected snips are available, null is returned.
