GraphFilter - it's a sweet tool found at animationbuffet

Description:

Allows the user to filter which curves are visible in the graph editor. Works with multiple selections as well as custom attributes. Saves you the trouble of scrolling through the object list and ctrl-selecting all the x-translate curves (for example).
Creates a pop-up window with a list of all keyable attributes of all selected objects.
Simply select the channel (or channels) and hit the "Filter Selected" button.
Has "replace" & "append" modes and a Graph-Editor toggle button.
