Help Android Assistant question

[ThisIsGoofy]

Simple question I'm sure but I can't find the answer by Googling or on youtube. Can anyone tell me what the icons at the bottom of the screen in the Tools portion mean? I'm pretty sure one is for Wi-Fi and one for airplane mode but I don't know about the other three. This seems like a helpful app. Oh, another question...I killed the calendar from the Process list---any way to get it back? Thank you very much!

From left to right: Bluetooth, WiFi, GPS, Data Sync, Airplane Mode

This is a guess because I don't use the calendar and it keeps opening no matter now often I kill it, lol, but if you just open it then go back into AA it should be running again; long press on it to add it to the ignore list and it won't be killed from then on.
