There may be times when you may need to navigate through an application without the use of a mouse (for example if the mouse stops responding and you need to save some data). In Windows, you can navigate through most screens with the arrow, tab and alt keys. Let's use IE in this example. Open an IE window. Look at the top toolbar (file, edit, view, favorites, tools...). Click the 'alt' button on your keyboard. You will notice that various letters are underlined.
Press the 'f' on your keyboard. As you can see, a menu drops down under 'file' (the same thing would happen if you press the underlined letter under any other of the toolbar items). If you select any of the letters in the menu, it will act the same way as you clicked it with your mouse.
For example, if you press 'O' for 'open', IE will bring up a dialog box that will allow you to open a stored web page (or any other file that IE can handle).
As an alternative to pressing the underlined letter in the menu, you can use the up/down arrows to step through the menu.
Using the TAB Button:
The tab key will typically move the cursor through the various text fields or to the various buttons in the active window. In the IE window set up as it is in this tutorial, the tab moved the cursor from the Google text field to the address text field.

This site was started for pages/information that didn't fit well on my other sites. It includes topics from backing up computer files to small engine repair to 3D graphics software to basic information on diabetes.
This site introduces you to macro photography. Macro photography is nothing more than the photography of small objects. It can take quite a while to understand the limitations associated with this type of photography. Without help, people will struggle to get good images. Understanding what's possible and what's not possible makes the task much easier. If you need to photograph relatively small objects (6" in height/width down to a few thousandths of an inch), this site will help.
If you're interested in air rifles, this site will introduce you to the types of rifles available and many of the things you'll need to know to shoot accurately. It also touches on field target competition. There are links to some of the better sites and forums as well as a collection of interactive demos.
