I agree with Rick, when I write a game in C++, I don't want it be infected with Lua at all, and wasting valuable memory for its GC and interpreter. I need all memory for my game to get the maximum content at maximum speed (everything loaded into memory makes things much faster).
But like I already said to diedir, if there would be a way to make the 2 keystrokes less (well actually 3 keystrokes, since there is Alt-Tab between them too).
Maybe F5 in Editor could be programmed to switch to the Code::Blocks IDE window, and then send a F9 keystroke. That would actually work! Then you can use your favorite language and your favorite IDE, and only the window class and F9 key would need to be configured in Editor. And you would have a debugger too for all languages.
