Saving an unsaveable file from a website!
This is a great tip submitted by Nick Brian: saving anything from any website! In Safari, in any website, you can click "Command-Option-A" (Command-Alt-A) to bring up a list of opened website with all the different files: pictures, video, audio, etc. One of the thing that this solves is on YouTube. YouTube doesn't let you download a video. With this, you simply have to use this keyboard shortcut, select the video file (I quickly spotted it as it was bigger than everything else (3 MB) and it was currently being downloaded) and double click to download it. The YouTube video file didn't play back in QuickTime but it worked just fine in VLC!
