RKGDuck is a handy free tool that can save you considerable time on small SEM projects.
RKGDuck slides a snippet of perl (or a big honking mass of perl, should you so need) into the Windows cut-and-paste clipboard buffer. This lets you do powerful text transformations within and between all Windows apps, using the familiar Control-C (copy) and Control-V (paste) mechanism.
After cajoling your local perl geek to write a tiny filter for your task, you can share that functionality easily with less-technical users, and you don't have to install perl on the end-user machines.
Here's a new RKGDuck video showing how in a couple minutes you can write a powerful filter to help clean up keyword lists.
You can watch other how-to videos and download the app itself on the RkGDuck homepage.
