[feature request] View item in timeline icon/action button

[Kevin-Hamilton]

In the timeline view, when hovering over a timeline item, there is an action button with a pencil icon which when clicked will focus the edit caret in the markwhen document editor on that item.

It would be nice if there were a similar action button that would appear when hovering over an item in the document editor, which when clicked would bring that item into view in the timeline view.
