Shortcuts for Win XP like the Palm graffiti shortcuts

I really enjoy using the graffiti shortcuts on my Palm and was
wondering, is there a "similar" option for Windows XP so that if I type:
".mt" it will put the word "meeting" in any document that I am typing
e.g. notepad, wordpad, or any text box/address bar.
I know there is no "ribbon" shape squiggle for the shortcut key like on
a palm so using the "." as a prefix would help.
I am guessing a 3rd party option would be needed but am not sure what it
will be called in a Windows environment (macros perhaps...?)
Thanks
