[arch-general] How do I uncomment a locale?

Hi, I am busy installing Arch core and am stuck at configuring the locale-gen part of the process. I am asked to uncomment the locales I need. Does this mean to delete them? There is a long list of them and I presume I need to delete all except the Australian ones (in my case). Do I simply delete them from this screen?
