Use of mobile Actions icon on Desktop?

Looking for help in designing a navigation method (visual affordance) for space constrained Desktop app.

Below, I have a tree grid which is the primary navigation for the detail pane below the grid. Each level within the grid can have multiple nodes/children.

(It is possible for the user to basically hide the grid via a slider or to maximize the grid via the same method.)

Specific questions are: 1. Arrow up icon next to a 3rd Level Name for moving up in the grid from the navigation panel. Is this viable? Intuitive? planning for a mouseover. Is there a more elegant way- Win 8?- way to do this?

  1. Next to the 4th Level label and dropdown control, I have a mobile (iOS) Actions icon with a menu of actions- is this mixing metaphors? Is there a better icon or even better paradigm? Space is an issue.

The goal between these two (and they are a bit redundant here, but this is to explore options not final desing) is to enable a user to navigate the hierarchy from the details.
