Recently I was on the phone with one of our users and the conversation was geared around navigation and the amount of time that it took to go from screen to screen.  I was a bit confused since we have gone to great efforts to make sure that navigation was as fast as we could make it.  After further discussion, I learned that he was always using the mouse and the next and back arrows at the top of the screen.
Using the Screen Swipe
A feature that was implemented awhile back is the screen swipe which allows you to simply swipe the screen right or left depending on the direction that you want to go.  To do this, simply touch the screen with your finger (or click and drag with the left mouse button) and begin the swipe and you will see the screen begin to move.  In the screenshot below, the screen is being dragged to the left which will navigate to the next screen.
Conversely, if you wish to go to the previous screen, simply drag the screen to the right.
This functionality works on all screens and even when using a mouse, can save a lot of time so you don’t have to move your arm and/or the mouse all the way to the top left of the screen.
Mouse Right-Click
The mouse right-click has been in the software since the very beginning of time (not to overstate the longevity this feature has been in place).  However, many people have never been informed about this navigation tool or simply had forgotten.  When using a mouse, the right-click will move to the next screen.  In the scenario that a downstream screen has been loaded (i.e. an answer screen) and the only direction to go is backwards, then it will navigate backwards.
The right-click has the logic to know which is the proper screen to load next and saves the need to go up to the menu area and click the Next button.
Adjust Swiping Distance
Each user can adjust the swiping distance required in order to register a page swipe. Â To do this, open up the User Preferences. Â By default the distance is 150 pixels, but this can be adjusted to suit your needs. Â When the size is modified, the green bar will show the distance that will be required in order to trigger the page navigation.
