BetterTouchTool has a lot of overlap with AHK I believe. Lets you remap keyboard/mouse actions globally and/or per application and perform actions or run scripts on keyboard/mouse input ands lots of features of that kind.
(Never used AHK myself but the couple times I looked for something similar to BetterTouchTool on Windows I got recommended AHK)
