But IMO it's best not to try to make one program emulate the behavior of another, but rather embrace the advantages and disadvantages of each program to make each work to it's best ability...
For me, it's about the best implementation of a feature. LR has that better implemented than C1 and it makes sense to try to emulate it (if possible). There are other things that C1 does better (customization of toolbars/tools for example) as well.
I decided that I will use LR for certain things and C1 for others. While C1 was my first RAW converter, I would never use it for working on weddings anymore. LR has a MUCH better workflow than C1. I do use C1 for portraits where the volume of images is much lower and the workflow doesn't get in the way too much. Yes, you can create shortcuts at OS level, but that's a backwards way of implementing it (and what about Windows? Is it possible there?) and then you have to make sure you don't have any conflicts within the app (there is no warning since they don't communicate back and forth; within the app you do get a warning). Again, not saying it's not possible, but a pain (although Doug might have a higher pain threshold than me
).
So, maybe the solution is to try to see where each one fits within your workflow. Luckily for users, there are both mature applications and you get great output from both nowadays (they will always up one another in certain areas, but overall they are both good).
