 ## Support 
 The OS X and Linux machines are managed by Computer Science Support (CS Support). If you have a problem with a machine, please contact CS Suport by email [cs-support@aber.ac.uk](mailto:cs-support@aber.ac.uk) or go to the office FIXME in the Computer Science building. Tell them which machine you are working on; you can find that information FIXME.

 ## File Management 
 
+### Finder windows 
+
+#### Tabs 
+It is possible to add tabs to a Finder window. To do that, select a Finder window and either press Cmd+t or select `File > New Tab` from the Finder menu bar.  
+
+### Quick access to document in Finder
+If an application window displays a document from the filestore, there is a handy way to find out where it is located in the Finder. Whilst this doesn't work in all windows, the general tip is that if the filename is displayed next to a mini-icon for the file, you can use this tip.
+
+With the mouse pointer over the filename in the header bar, press the Cmd key and the (left) mouse button. A popup will be displayed, which shows the path from the file to the root of the filestore (in reverse order). You select any item on that popup list to quickly reveal the item (file or folder) within a new Finder window. 
+
+### Viewing a specific folder
+Some folders are hidden by default on OS X. You can quickly navigate to other parts of the filestore by entering the path into a Finder window. Either press the shortcut keys Shift+Cmd+G or select Go > Go to Folder... from the Finder menu. A sheet will drop down in the current menu, as shown below.  
+
+![Go to Folder](images/finder-goto-folder.png) 
+
+Enter the file path and press Go (or the Return key) to display the contents of the folder.
+
 ## Application Management 
 
 ### The Dock 
 
 ### The Apple Menu 
 
+### Stopping unresponsive applications (Force Quit)
+If an application becomes unresponsive for a period of time, you can use Finder to terminate it. This is the visual equivalent of using the Unix kill command. To display the list of applications that can be closed, press the Cmd+Option+Esc key combination. A small window is displayed; an example is provided below. 
+
+![Force Quit Dialog](images/force-quit.png) 
+
+The above dialog shows that all applications appear to be active. If OS X thinks that an application is unresponsive, it will add a short description next to the application name. If the application doesn't have that extra description, give it a bit longer to see if it becomes responsive again. 
+
+If you do need to stop the application, select the application from the list and press Force Quit. In most circumstances, that will stop the application. If the application refuses to quit, you might need to open the Activity Monitor application or open the Terminal to run kill.

+Whilst this isn't visible on the iMac keyboard, simply type the Option+3 combination to insert the # character. The option key is often referred to as the alt key. 
 
 ## Diacritics 
 To insert a character with a diacritic, press and hold the character. For example, to add the character é (e-acute), press and hold the e character. A popup selector will be displayed.

 Preview is a built-in application that can view PDF files as well as various graphic files. It is less known that Preview is very useful for manipulating PDF files. It can be used to add notes and other annotations, for combining files, changing the orientation and order of pages and some other useful operations. 
 
+## Print to PDF
+You can output a PDF file from any application that uses the standard print dialog. To do this, open the print dialog (Cmd+p). A dialog similar to the following is shown. 
+
+![Print Dialog without Details](images/pdf-print1.png) 
+
+This is actually a condensed version. If you click Show Details, you will see an expanded version with more options. This can be handy if you want to print multiple pages to a single page.  
+
+![Print Dialog with Details](images/pdf-print1a.png) 
+
+On the bottom left of the dialog, you will see the button PDF. Click this and a menu will be shown. 
+
+![Save to PDF](images/pdf-print2.png)
