Sticky click bar on Macbook Pro 15 track pad

In trying to fish out a hard crumb stuck in the narrow gap between the click bar and the frame on the track pad, I've managed to shove part of it firmly under the bar. It's making the click unreliable. Does anyone know how I can remove the bar and get the dirt out? I've removed keys before by slavishly following a video on how to do that, but I can't find one on removing the click bar. Is there one?

Thanks in advance for your help!
