I use True Launch Bar for my Start menu manager, and it has all these hotkey capabilities built in. But if you don’t already depend on something for your hot keys, Wise Hotkey Pro looks like a very good program. Just remember to add the few things you use most at the start – the ones where you’re tired of searching for the icon. If you load it up with lots of programs, you’ll have a hard time remembering which keys do what. So grow it slowly over time and you’ll be amazed at how quickly you grow to depend on it, and all the time/annoyance it saves you!
Also, I’ve used other tools from Wise and they generally work well, not too much memory/space needed, do what they say without a big learning curve.
