does anyone by chance know anything about the L1+L3 thing? i am quite positive when i press Start to open the Main Menu it shows an indicator for L1+L3 to do something called, 'Toggle Modes'. when i press L1+R3 for mouse mode there is an indicator for L1+R3 to 'Exit'. and the indicator in Main Menu is larger. and looks nothing like an R but looks like an L. maybe SE just placed the wrong indicator?

i dunno. but it is still rather curious. :/
