Keyboard HotKey/Macro software?

Hi,

I have been using a old version of KeyText for a few years but would like to switch to a better tool because there certain features which my current version does not have. Most importantly, I want my defined hotkeys organized as categories.

I did use Google before making this post but got overwhelmed by the number of possibilities. Can someone kindly recommend a good tool (preferably freeware if possible but shareware will be equally good).

Many advance thanks.
P.S
I'm currently using XP pro 32 bit but am considering moving to Xp 64-bit or Windows 7 (64-bit) in the future.
