Degree of Interest
After you have activated a task, Mylar builds up a degree of interest model
and uses this model to filter Eclipse views. Press the Mylar glasses on
the view to toggle the filtering. To temporarily un filter a node Alt+click it.

You can also directly manually manipulate the
interest level of one or more elements by right clicking them and using the two
Mylar actions in the popup menu. Keyboard shortcuts for these
are Ctrl+Alt+Shift+Up Arrow for Make Landmark, and
Ctrl+Alt+Shift+Down Arrow for Make Less Interesting.

Resources that are always
considered interesting can be configured to always show when the
interest filter is on, via the root Mylar preference page.
Note that the parent of the resource, e.g. the project or folder,
needs to be interesting for it's children to show.
