How to use a PC or laptop without a mouse... May come in handy..

1: Opening the Start Menu
To start off, you can access the Microsoft Windows Start button and Start Menu by pressing the Windows Key on the keyboard or by pressing the Ctrl and Esc keys at the same time.

Note: Because Windows 8 does not have a Start Menu, pressing the Windows key or Ctrl+Esc keys shows the Windows Start screen or go to the Windows desktop.

In the Start Menu, you can use the arrow keys on the keyboard to move up, down, left, or right within the Start Menu. Once you've located the program you want to run, press the Enter key.

2: Opening a program on the desktop
If there is a program you want to run that has an icon (shortcut) on the desktop, you can move to the desktop by pressing your tab key on your keyboard. Pressing tab while on the desktop will switch between the desktop, the Start button, and each of the items on the taskbar. You can determine what area you're currently at by looking for an item that is selected. An item that is selected will either be highlighted or have a border of dots.

In some cases, you may have to press tab several times before getting to the desktop icons. Once one of the desktop icons has been selected, you can move to other icons by using your arrow keys.

Once the icon on the desktop you want to run is selected, press the Enter key to open that program.

3: Closing, minimizing, maximizing, or moving a window
Closing a window

Press the Ctrl and F4 keys on the keyboard at the same time to close the current open program or window.

Users may also press the Alt and spacebar keys at the same time, then arrow down to the Close or Exit option in the menu and press Enter.

4: Minimizing or shrink a window

To minimize a window, press the Windows key and down arrow at the same time (sometimes twice).

5: Maximizing a window

To maximize a window, press the Windows key and up arrow at the same time.

6: Moving a window

Before you can move any window, it must not be maximized. To make the window appear in windowed mode, press the Alt and spacebar keys at the same time, move to the restore option, and press Enter. In windowed mode, you can move a window if you press Alt+spacebar, choose Move from the menu, then use the arrow keys to move it.

7: Closing or changing tabs

In most programs, pressing the Ctrl and F4 keys at the same time closes a tab.

8: Switching tabs

To move left to right between tabs in the currently selected window, press the Ctrl and Tab keys at the same time.

To move right to left between tabs in the currently selected window, press the Ctrl, Shift, and Tab keys at the same time.

9: Moving between open windows and applications
To move between any open programs on your computer, press and hold the Alt key, then press the Tab key. If this is done successfully, a window appears that displays each of the open programs on your computer. Repeatedly pressing Tab while continuing to hold Alt moves between each of the open programs. When the program you want to switch to is selected, let go of both keys to make it your current window

10: Navigating between fields and buttons on a window
To move your cursor between objects of fields within a window (such as a dialog box), you'll often use the Tab, spacebar, arrow, and the Enter keys. Tab is usually the default, but if it does not work, try using the arrow keys. If you need to press a button, such as OK or Cancel, press the spacebar or Enter key.

11: Manipulating and moving through text
Below are the different methods of how you can move through text in a document without the aid of a mouse. Not only does this help users who do not have access to a mouse, it can also save you a great deal of time when working with text documents.
Arrow key - Using the arrow keys on the keyboard will move the cursor up, down, left, or right in the document.

Ctrl and Arrow keys - Holding down the Ctrl key while pressing the left or right arrow keys will move the cursor one word at a time. Using this shortcut is much faster than only using the arrow keys. Holding Ctrl while pressing up or down moves through each of the paragraphs in the document.

End and Home keys - Pressing the End key takes you to the end of a line or document, while pressing the Home key will move you to the beginning.

Shift key - The Shift key allows you to highlight text. For example, holding down the Shift key while using the right or left arrow keys will highlight the text to the left or right. If you hold down shift while pressing the down arrow keys, you will highlight one line at a time in that direction.

Finally, you can use the Shift key in combination with the other above recommendations. For example, pressing and holding Shift and Ctrl and using the arrows will highlight a word at a time. Holding down Shift and pressing the End key will highlight from the current cursor position to the end of the line or document.
