`g:zettel_link_following` can be set to `cursor` or `line` to change the way zk detect the closest link to follow to (or create a new link for). Setting it to `cursor` will look for the current word under the cursor and decide if it is a followable link. `line` will look from the current cursor position to the end of the line instead.
