Antechinus C# Editor includes VB macro scripting engine, which is a powerful tool for automating tasks you frequently perform. The color-coding, auto-complete and Intellisense are there to speed up the generation of scripts.

Running this simple script changes the application size and position. Try clicking the right mouse button when you are in the Script Editor window to bring out the context menu and experiment with the options. List Functions, for example, gives you all the predefined VB functions you can use. Try clicking one of them to see its declaration and parameter list.
