Comments

Call MCSGetDlen2 on the item you want to read from, to select it. After doing it you can use this syscall.

Note that between the call to MCSGetDlen2 and the call to this syscall, process switching cannot occur, i.e., one can't call anything that allows for entering the menu or switching to eActivity (in the case of eActivity strips). So, make sure you do not call GetKey between the calls to these syscalls.
