AutoCAD 2015 and its verticals do not include the horizontal scroll bar for viewports. Personally, this is a feature I have never used since it was introduced, and in fact is one of the first things I disable in a new install. But one of the quickest ways to find out if something is being used it to take it away, and there are obviously a lot of people who prefer to have the horizontal scroll bar.
The current Autodesk Knowledge Network article on this topic originally did not offer much help other than to reinforce the fact that the horizontal scroll bar is not available. A few weeks later, they did update the document to say that you can use the middle mouse button and the Shift key. It should be noted that the -Pan command with Ortho can also constrain the movement to horizontal or vertical.
In Civil 3D, you can use the Ctrl Key to alter the selection of certain objects. For example, if you select a single alignment geometry point label, the entire string of labels are selected. However if you hold the Ctrl key and select a single alignment label, only the label you pick is selected. This is useful if you want to delete a single label. The same thing applies to grade break labels on a profile.
Selection of one alignment label, entire string is selected.
Selection of one alignment label while using the Ctrl key, only that label is selected
If for some reason the Ctrl assisted selection method does not work, check the value LEGACYCTRLPICK. When this is set to 1, the Ctrl key has no effect when trying to select a single label.
A while back we had a Twitter conversation with @AutodeskHelp and @TommieR on UNinstall procedures for various Autodesk products. Autodesk has published articles regarding the removal of Civil 3D 2009, 2011, and 2012. For whatever reason, there is nothing on 2013, and the articles that do exist do not cover the removal of every component installed with Civil 3D
Recently we had the task of performing a few Uninstalls of Civil 3D 2013 and the order of Uninstalls shown below seems to work successfully. This is not the only order that will work, but there are certain things that must occur. For example, you have to remove the Storm and Sanitary Analysis Plug-in before removing the Storm and Sanitary Analysis component itself. Read more about Uninstall Order of Civil 3D components
