Is there a recording function in MacroMonkey?

If not how do I start?

Tks in advance.

For keystroke and mouse click type recording?

MM doesn't have that kind of recording functionality.
Maybe you could using a script and polling things fast, but would probably still missing something.
There are no current plans to add a proper facility for doing this currently.

i.e. i must learn the LUA language and write the codes on notepad?

Look here:

You can use just Notepad but it's much more productive to an editor with at least some minimal syntax highlighting.
I like "EditPlus" if nothing else because I've been using it so long, but there are a lot of free ones out that should
work well.
Just needs to have a Lua profile for it.

I wanted to have my own optional IDE (Integrated Developer Environment http://en.wikipedia.org/wiki/Integrated ... nvironment) as to make MM like ACTOOL, etc.
ACTOOL allows you to edit, run and debug scripts in the same place.
Incidentally I might have kept on using ACTOOL but it's biggest problem is it's custom script language that has a lot of bugs and is not near as robust as Lua.

There are some pretty good open source editors and IDE but they would take a lot of work to make the quality product I'd want.
