Once again we have to inform our readers of new actions that have been discovered in OS X Yosemite. Many have been the occasions in which we have indicated that the system of the bitten apple in addition to the functions that they have at a glance, they have many other hidden that users, and especially OS X developers are finding.
Apple has never stopped to publish an extensive manual on how to use its operating systems and it is making use of it or reading the tricks that most of the time they are born from application developers work for the same, that we know new actions like the one that we are going to explain to you today.
In this case, the trick that we are going to tell you today has to do with the multi-touch gestures that we can do in OS X Yosemite with the computer's Trackpad. The fact is that it seems that if in a certain website we have a link, a link to a website different from the first, simply hovering over the link and making a three-finger tap on the Trackpad, OS X Yosemite will return a preview of the website destination of that link.
But the thing goes further since it is not that it shows us a static image of the website of destination but allows us to view the entire web by sliding two fingers up or down as we normally do in a website in Safari. However, this action requires a small configuration in the System Preferences, more specifically in the Trackpad section.
To activate the pulsation with three fingers we must enter System Preferences> Trackpad and in the tab Point and click, we must activate the option Search (Tap with three fingers).
