quartus 11.1 "auto-complete" problem

hi all:

now i am using the newest version quartus 11.1,one of the new is that the text editor will "auto-complete"(i do not know the exactly word of that :p) the defined words.but one of the question is the case translation.for exemple,i define a reg"reg FPGALED",then when i write"fpg",the"fpgALED" will popup. if i press enter,editor wii auto complete the word with fpgALED.i do not know where can i set the option to aotu complete with the defined word.
