It should be possible to hit alt+(1-9) to shout "Starboard", "Room" etc. and we should be able to define and save such sentences.
Very few of us knows that this feature allready excists , though without any predefined variables or the ability to save them. Just enter a chat line, and instead of hitting enter, hit alt+1 (or 2-9). The line will be sent, and saved under that key. To send it again, just hit alt+1 (or 2-9).
