Mapkeys are created by recording picking step by step from "menu". I assume you want reactivate yours mapkeys b/c you reload Pro-E or up garde to newer version of Pro-E. If you still using WildFire then yes you still can reuse the mapkeys that you already have (store in config.pro). But if you are switching from Wildfire to Creo, b/c the "lay out" between WildFire and Creo are different. WildFire is using "menu" and Creo is using "tab". Depend on what you have, some of your mapkeys still work, but I believe most of them don't. Look like you have to create you mapkey from scratch.
