Sometimes when you get sent a link to an mp3 file or something similar, you just want to download it. Usually you’d have to open it in your browser, wait for it to load and then save it. Here’s what you could do instead:
Open Automator and create a new service, follow the steps in the image below and save it. Then open System Preferences and go to the Keyboard pane, locate the service you created as per the second image, then double click in the circled region to set a keyboard shortcut (I chose ⌃⌥⌘D).
Now I just select the url of the content I want to download, press ⌃⌥⌘D and boom.

0This is a really great idea from Keith Lang, co-founder of Skitch. It’s actually quite an old post now, but I thought it was worth bringing up again because the new generation of small-screened, ultra-portable notebooks will need this kind of behaviour more and more.

0Hold down the Option key while your mouse is hovered over the image, and it will change to a magnifying glass. Once you’ve zoomed in, drag the cursor, use the scroll wheel, or two fingers on a trackpad to move around the image. Press Option-Shift, and then click on the picture to zoom out.
