I haven't used Pro Tools SE, but in PT9 you can use Track List in the MIDI Editor.
Look at the bottom, left corner of the MIDI Editor window. Is there a white, right arrow? Clicking on this will open the Track List.
I've just watched this SE video:

There doesn't seem to be a right arrow to open the track list.
He just seems to highlight the name of the track or the region for it to be displayed in the editor.
