From the official announcement:
VMware Fusion 1.1.1, a free update for current VMware Fusion customers and available in all the languages Fusion currently ships in, also adds a nifty new feature to transparently remap keyboard shortcuts when going back and forth between applications in the virtual machine and the Mac, regardless of what view the virtual machine is in.
For example, VMware Fusion now remaps Command –X from the keyboard to Ctrl-X in the virtual machine whether in Full Screen, Single Window or Unity. The same remapping happens for Command-Z/-C/-V/-P/-A/-F. Previously, VMware Fusion only did this remapping in Unity mode.
What this means to users, is that when copying something from the Mac side to paste into the virtual machine, and vice versa, you no longer have to remember “Is it Ctrl-V, or Command-V to paste here? Which machine am I interacting with?”
The effect is a more integrated blending of the two operating systems, so your Mac and Windows work together seamlessly, where the user only has to remember one set of keyboard shortcuts!
Keyboard remapping can be turned on and off in the VMware Fusion > Preferences dialog.
