Keyboard shortcuts for Twitter

You may not know that the Twitter Web interface lets you use keyboard shortcuts to quickly complete certain tasks, navigate, and select certain timeline views. For example, if you want to DM someone, just hit 'M'; or if you want to retweet a tweet, open it, then press 'T'. To see a list of available shortcuts, on the Twitter Web interface, click the Gear menu and select "Keyboard Shortcuts." You should see a list like the one below.

Editor's note: I tested many of these in Chrome (Mac OS). Most work. A few, like Retweet, did not work for me.
