Feature: Be able to bind shortcut keys to the toolbar button "Show passing tests" (and thus probably also "Show failing tests", "Show unexecuted tests" and "Show ignored tests").

Scenario: I am looking for a specific test so I browse through tests and dbl click/investigate it in the hierarchical view. When I found test I want to work with I pin it via kbd shortcut (since I am in the editor after I just dbl clicked it) and now I want to hide all passing tests in 'NCrunch Tests' window to only show my pinned one.

Current behavior: I must use the mouse to find the toolbar button "Show passing tests", click it, then get back to editor.

Desired behavior: While still in the editor (and hands on keyboard) with test I just pinned, I want to toggle the toolbar button "Show passing tests" via a keyboard shortcut.
