Help What the heckk does this button do?

[jhat3k1]

I cannot figure out what the button with the three horizontal lines, between the gmail and end buttons does? It doesn't mention the button in the manual. Has anyone figured this out?

this same icon shows up on some screen views also. it means more info however it does not work when in those screens.. perhaps a software update...
