One thing I really like about stackoverflow.com is that you end up learning as much answering questions on there as you do by asking them.
For example, when I saw this question I was sure there would be a way to delete a region by simply starting to type after selecting the region, but I didn’t know how. However given that this is emacs, I seriously doubted the person asking the question would be the first one to want this particular feature.
Sure enough, a quick dig around EmacsWiki brought up delete-selection-mode which does exactly what the poster wanted. And I’ve learned a little bit more about Emacs, again.
At this rate I’ll be reasonably proficient in Emacs in a decade or two .Google+
