• vim - open file with complete path

  - by David Oneill

  If I have a file that contains a complete path for a file, is there a way to highlight the filename (using visual mode) and open the file? (preferably in a split screen) As I think about it, here is what I would like: if the file name contains a / character, assume it is a full path (IE the 'current directory' is root). Otherwise, use the current folder (IE default behavior) Is this possible?
