I did a little more testing on that and it seems that U, I and B are not working together with command key. These are the short-cuts usually used for underline, italics and bold in word-processors. Since editorial is not using them, it would be nice to be able to define short-cuts for user defined workflows.

I just want to give this my +1. A simple option to keep the location of the preview at it's previous position would already help a lot.

I want to assign a workflow to command-u. The shortcut is accdted in the menu, but it does not work in the editor. Other, similar shortcuts do work, like command-o and or command-f (overwriting the internal find workflow). Is there anything special with command-u or is it an issue with my Bluetooth keyboard? Can anybody reproduce?
