What I mean is this:
[[to_somefile2|This is a link]]
[This is a link](to_somefile)
In the first case, in edit mode, the link is underlined when the mouse hovers over it, and a cmd-click opens the link in a new pane.
In the second case, the link is completely non-functional in edit mode. You must switch into preview mode in order to follow the link and open it in a new pane.
Why is the behavior different for two links with ostensibly identical functionality: one standard markdown format and one wikilink format?
