Capture All Keyboard Input

First off, I know this could be used for a keylogger. I'm not going for that, I'm looking to make an application that listens for custom key combinations just to automate a few really annoying tasks.

Is there some way to capture all input f开发者_Python百科rom the keyboard?

You appear to be looking for RegisterHotKey().

I don't think you want to hook all keyboard input. You simply want an app with a hidden window listening for WM_HOTKEY. I don't think you even need to write it yourself. There are a lots of utilities that will do it for you and let you associate system-wide hot keys with actions of your specification, e.g. AutoHotKey.
