Keyboard macro app

I've been using Perfect Keyboard for a few years but the company Pitrinec seems to have gone.belly up and for some reason, my copy has died also. So I couldn't reinstall it.

This allowed me to set macros like .s which enters my signature or shows a menu of several signatures for me to choose. I also set .w which would accept 'wouldnt' and output 'wouldn't'. Along with many others with infinite variety.

Is there another app out there to do this kind of thing?
