Nifty! AutoHotKey a simple scripting language for windows in which you can define shortcut keys and hotstrings. Damn I like it a lot!
Here’s my test case, as described in the quick start tutorial:
#z::Run www.google.com
::btw::by the way
save this as a .ahk file. Double-click on it and it’s running.
Now you can press “the windows key” + z to go to Google (the first line) - or as of now when you type “btw” it will automagically be replace by “by the way” (second line).
