To be clear, most of the time I am absolutely aware of what key combinations or functionality do what. However, there are some rare ones I am using once or twice a year and I always forgot and need to google it.

The second type of shortucts and useful functionality are children of accidents, I accidentally hit those and I figure out a new functionality. In this blog post, I try to collect the accidental ones as well as the I need it once a year.
