Rig and paint weights like XSI

[Talik]

Hi guys. I'm new with Maya. I'm confused a little bit with Maya paint tools (or I don't know about it's functionality)
Maya is been represented as superior animation and rigging tool but I've found no hotkeys in painting weights. Is there any option to make them? I cannot imagine painting weights without hotkeys.

Also I have not found any similar tool like "move joint tool" in XSI and "link tool" in 3ds max
