I'm looking for something that will read and record my keystrokes until I disable it, then once I activate it the mod will replay my keystrokes making my player preform the same actions. Is there such a thing?
Based on the description, it seem like Macro Maker is what you're looking for, though it is only for 1.7.10, and GitHub issues include comments indicating the author has stopped developing it.
If you want a macro mod for a newer version of Minecraft, you could look at Advanced Macros, but it doesn't look like that one has a recording mode.
Great! Just what I'm looking for, thanks
