I LOVE AutoHotKey. It expanded strings for me. It moved windows around and resized them. It added the hotkeys that developers forgot. AutoHotKey is a marvel and, amazingly, it's free. I could even, somewhat painfully, create a GUI with it if I wanted to.
But now I'm on a Mac full time and there's no equivalent. Finally forced to deal with it the best I've done is replace it with a half-dozen different tools.
Spectacle (free) or Divvy ($) can move windows around and resize them. Options are limited, but I'm finding them adequate for now.
KeyRemap4MacBok (free) will... remap keys. Mainly to move cmd-q to cmd-shift-q so I'll stop closing my browser when I meant to close a tab.
BetterTouchTool (free) has added the back/forward gestures that were missing from Finder and seems to have a LOT more functionality that I haven't checked out yet.
Typinator ($) or TextExpander ($) will expand text although there are some issues with Mac's "secure keyboard mode" and applications (especially Chrome) that don't it turn it off when they're done with it. Typinator is winning this battle so far and their support was very quick to respond and fix my issue with one app that it wouldn't work with.
It's not perfect but it's the best I've found so far.
