I guess without another key to the left a lot of people remap caps-lock to ctrl. I never got used to that for some reason. In general terms I tend to avoid remapping in order to maintain a consistent UI. the only exception to this that makes sense to me is that all of my Macs have always had their keyboards remapped to match a PC. As closely as reasonable and possible. For example, ctrl-c and ctrl-v do exactly the same thing whether I am running a Windows, Linux (GUI) or MacOS machine.
