My user profile has gone nuts today, so I had to recreate it. The biggest part was to reconfigure shortcuts. And it was hard also, because I use some shortcuts, which are predefined for something else - so I need first to remove the current connection and then create a new shortcut for the function I need. It could be however easily solved by exporting the shortcuts.
Same applies for example to embedded content rules - why cannot we export only those? It would make creating specific file types or modifying existing ones so much easier...
