A really simple way to change this manually, if you're so inclined:
First step, install the "make it so" patch in preware.
Second step, open up internalz pro (install it from preware if you haven't already).
Go up directories from media/internal until you are at root.
Go to /usr/palm/sysmgr/localization/en_us
There, you will see a file called strings.json.
Make a copy of that file - copy it somewhere you wont lose it like media/internal. You'll need that file later if you intend to revert this change (or remove the "make it so patch", it will have to be original for removal to happen).
Now tap on the strings.json file and hit open. It will say:
"Just type...": "Make it so..."
All you have to do is change the text where "Make it so..." is, then save the file and reboot the touchpad (full reboot, NOT a luna restart).
So in my case, I changed it to "Just type...": "How may I please you, Master?"
I started a similar thread a few weeks ago and Jason provided an patch that made it easier.
