Top 10 computer mouse tips everyone should know

Most computer users don't take full advantage of the computer Mouse. Below are computer mouse tips and secrets that help you get the full potential of your computer mouse and increase your overall productivity while on the computer.

Shift key and mouse click

Many text editors and programs allow you to highlight all or portions of text using the Shift key and the mouse. For example, place the cursor at the beginning of a paragraph, hold down the Shift key and click at the end of the paragraph to highlight the full paragraph.

Take full advantage of the scroll wheel

Today, everyone is fully aware of a mouse wheels ability to scroll up and down on a page. However, this wheel can also do so much more, as shown below.

• The mouse wheel is not just a wheel, it can also be used as a button. Pressing down on the wheel will act like a third mouse button. This can be used to open a web page in a tab by clicking the wheel on any link and can also be used to close a tab by clicking the wheel on any open tab.
• Quickly Zoom in and Out on a web page, word document, excel spreadsheet, etc. by holding down the Ctrl key and scrolling up to zoom in and down to zoom out.
• Move forward and backwards while browsing the Internet by holding down the Shift key and scrolling up and down. Scrolling down goes back and scrolling up goes forward.

Select with double and triple click

Any word can be easily selected by double-clicking the word. If you want to highlight the whole paragraph, click the mouse button three times on any text in the paragraph.

Use the right-click

Take full advantage of the right-click any time you highlight text or wish to view the properties of an object. For example, if you highlight a file or text, you can right-click that highlighted item copy it and then right-click anywhere else to paste it.

If you right-click on any file or text and drag it while continuing to hold the right button, when you let go you will be given the option to move or copy that file or text. This saves you the extra step of having to right-click where you want to paste the item.

Ctrl key and mouse click or highlight

While holding down the Ctrl key you can left-click to select multiple objects or highlight multiple sections of text. For example, in Microsoft Windows you could hold down the Ctrl key and click to select multiple files at once. If you wanted to highlight different parts of a paragraph or web page, you could also hold down the Ctrl key and select each section you wanted to copy.

Mozilla Firefox users can also hold down the Ctrl key and individually click on each cell in a table they wish to copy or drag their mouse down a row to select just that row or text without selecting any of the other text in that table.

Use the mouse side buttons

Many new computer mice have buttons on the side of the mouse. These buttons can be programmed to do anything, however, by default the left-thumb button can be used to go back on a web page. This makes browsing the Internet more enjoyable since you do not need to move the mouse cursor to the browser back arrow button in order to go back a page.

Use the Windows Snap To feature

Take full advantage of the Windows mouse Snap To feature, which will automatically move your mouse to buttons that appear in a dialog box. For example, if you delete a file or close a window you may get a prompt asking you if you are sure you want to perform the task. With the Snap To feature enabled, the mouse cursor automatically moves to the Ok button, so all you will have to do is click the mouse button if you agree. This saves you the time of having to move the mouse cursor over to the Ok button and then click Ok. To enable this feature open the Mouse properties under the Windows Control Panel and check the Snap To check box under the Pointer Options tab.

While changing this feature we also suggest looking at other available options in the Mouse settings. For example, increasing the Motion speed can also help increase your productivity while using the mouse.

Manage the open window with the mouse

Double-click the top title bar of any window to maximize a window or if it is already maximized resize it to a window. You can also double-click the icon for the window in the top-left corner of the window to close that window.

Move the mouse with your keyboard

Instead of using the mouse that came with your computer you can also enabel windows to use the number pad as a mouse.

Customize your mouse

Finally, if you have a mouse with more than two buttons, installing the included mouse software will allow you to customize the mouse even more. For example, if you don't use the side buttons to move back and forth in a web page change it to something you do more often, such as switching between open windows or opening the calculator.

WHAT IS IP(INTERNET PROTOCOL)

IP Short for Internet Protocol, IP is an address of a computer or other network device on a network using IP or TCP/IP. For example, the number "166.70.10.23" is an example of such an address. These addresses are similar to an addresses used on a house and is what allows data to reach the appropriate destination on a network.

There are five classes of available IP ranges: Class A, Class B, Class C, Class D and Class E, while only A, B and C are commonly used. Each class allows for a range of valid IP addresses. Below is a listing of these addresses.

Class	Address Range	Supports
Class A	1.0.0.1 to 126.255.255.254	Supports 16 million hosts on each of 127 networks.
Class B	128.1.0.1 to 191.255.255.254	Supports 65,000 hosts on each of 16,000 networks.
Class C	192.0.1.1 to 223.255.254.254	Supports 254 hosts on each of 2 million networks.
Class D	224.0.0.0 to 239.255.255.255	Reserved for multicast groups.
Class E	240.0.0.0 to 254.255.255.254	Reserved for future use, or Research and Development Purposes.

Ranges 127.x.x.x are reserved for loopback or localhost, for example, 127.0.0.1 is the common loopback address. Range 255.255.255.255 broadcasts to all hosts on the local network.

IP address breakdown

Every IP address is broke down into four sets of octets that break down into binary to represent the actual IP address. The below chart is an example of the IP 255.255.255.255. If you are new to binary, we highly recommend reading our binary and hexadecimal conversions section to get a better understanding of what we're doing in the below charts.

IP:	255	255	255	255
Binary value:	11111111	11111111	11111111	11111111
Octet value:	8	8	8	8

If we were to break down the IP "166.70.10.23", you would get the below value. The below fist row is the IP address, the second row the binary values, and the third row the binary value calculated to equal the total of that section of the IP address.

166	70	10	23
10100110	01000110	00001010	00010111
128+32+4+2=166	64+4+2=70	8+2=10	16+4+2+1=23

Automatically assigned addresses

There are several IP addresses that are automatically assigned when you setup a home network. These default addresses are what allow your computer and other network devices to communicate and broadcast information over your network. Below is the most commonly assigned network addresses in a home network.

192.168.1.0	0 is the automatically assigned network address.
192.168.1.1	1 is the commonly used address used as the gateway.
192.168.1.2	2 is also a commonly used address used for a gateway.
192.168.1.3 - 254	Addresses beyond 3 are assigned to computers and devices on the network.
192.168.1.255	255 is automatically assigned on most networks as the broadcast address.

Getting an IP address

By default the router you use will assign each of your computers their own IP address, often using NAT to forward the data coming from those computers to outside networks such as the Internet. If you need to register an IP address that can be seen on the Internet, you must register through InterNIC or use a web host that can assign you addresses.
