The problem that Search Commands solved for me is this: even after using Office 2007 for a few months, I still can’t easily find what I’m looking for, and still get frustrated having to look at many toolbar icons that I’ll never use. The way I solve this problem today is by either digging through the Ribbon and cursing, or using Google. Surprisingly, the latter method is often faster.
Search Commands solves that problem, by letting you "google" your Office 2007 commands, and find the right one. It might seem kind of odd to search for commands rather than use a menu, but consider that Word, Excel, and PowerPoint each have at least several hundred commands. It’s a lot faster to type a few keys than it is to browse and scan through a dozen drop-down menus.
If you like QuickSilver, Firefox search keywords, YubNub, the Unix command line, or other keyboard-oriented ways of working, you’ll probably find Search Commands a welcome addition. It’s not perfect, but it’s a big step forward.
One last thing: Search Commands is still considered by Microsoft to be an experimental feature, meaning that it might not be rolled into the Office 2007 code base. This is surprising given the positive feedback this feature has received, and we’ve known for over a decade that the majority of users like to search, not browse. So, if you like Search Commands, express your support here.
