Jumplists are part of the new Windows 7 taskbar, and also part of newer versions of the Microsoft Windows operating system.
The jumplists provide access to program related options basically. This can be the most recent documents of Microsoft Word, the latest visited websites in Internet Explorer but also options to create a task like sending an email or opening a new web browser window.
The latest dev version of Google Chrome is now offering jumplist support in Windows 7 and newer Windows versions.
The jumplist can be openedwith a right-click of the Google Chrome icon in the Windows taskbar. The Google Chrome jumplist is divided into four areas of which three are always visible and one only if the user has added at least one item to it.
Below is an example of how a jumplist can look like.
The Google Browser will display the most visited websites, the recently closed websites and tasks in the jumplist. The most visited and recent websites are directly taken from the web browser's history while the task allow the user to open a new window (either normal or in incognito mode).
This is of course only the way if the system is not configured to block the display of recently opened items in the taskbar. If that feature is disabled, Chrome will only display tasks and the program launch option, but nothing more when you right-click it.
You can right-click the taskbar of your Windows system, select Properties, and there the Start Menu tab to find out whether your system saves those information or not.
The fourth group only becomes available if you pin an element in the jumplist. This is for example excellent for quickly accessing favorite websites from the Windows 7 jumplist. The latest developer build of Google Chrome can be downloaded from the dev channel page. It is interesting to see that the Google Chrome development team has added jumplist support while the Mozilla Firefox team has not shown any signs that they intend to support that feature in the near future.

Update: Jumplist support has also been added to the Firefox web browser in the meantime. It is not a feature that I make use of at all, and I have decided to disable the showing of recently opened items there.
