TapeMouse

This mod allows you to farm/boat/... while doing other things, as you can un-focus the Minecraft window.

Since the 1.9.4 / 1.10.2 build, you can emulate any keybinding.

You can set the delay to 0 to emulate a continues button press.

It may behave derpy if you don't alt-tab out properly, it depends on what you are holding and what you are pointing at. 

Don't use this on a server that doesn't allow AFK farming.
It is detectable, and I'm not planning on making it undetectable.

Don't blame me if you are banned!

Use /tapemouse <off|keybinding> [delay]

To get a list of all the keybinding names, use "/tapemouse".
