Top 10 Facebook tips

Below is a listing of our top 10 tips for the popular social networking website Facebook.

• Hide users, games, polls, etc.

It quickly gets annoying seeing some users posts, game invites, polls, etc. Hovering your mouse to the right of the post and clicking the Hide button as shown below can hide any post. After pressing the button you'll have the option to hide that user or in the case of a Facebook application the option to hide that application from ever showing up on your profile.

To unhide someone or unblock an application click the Edit Options link in the bottom right corner of the news feed as shown below.

Greasemonkey and FB Purity

Although Facebook does not give you the option to hide friends, friend requests, or various notifications, these can be hidden using browser add-ons. If you're running Mozilla Firefox, Chrome, Opera, or Safari we suggest installing the Facebook Purity add-on.

• Update your privacy settings

Click Account in the top right corner of the Facebook window and then click Privacy settings to adjust who is capable of seeing what on your Facebook profile. We highly recommend going through all the privacy settings to verify your privacy is properly protected.

Anything that is not set to friends only or friends of friends can be seen by anyone searching on the Internet. Below is a few things we recommend for most users.

1. Under Search in Privacy settings uncheck Public Search Results. Adjusting the settings prevents users from finding your account and profile picture in search results such as Google
2. Under Application settings, make sure you're only allowing applications you want to have access to your information. Applications that you grant rights to can have access to your Facebook profile information.

• If you're curious to see how a program or web page connect to the Facebook API can see your profile see Tip135.
•   Use the Facebook top bar for navigation

Knowing how to properly navigate is vital if you want to get the most out of Facebook. Below is a brief description of each of the available options in the top bar as shown above.

Home (facebook logo) - Clicking this logo takes you to your wall (News Feed) that shows all friends recent posts.

Friend requests - If any friend requests are waiting to be approved this icon shows a notification of how many friends are waiting for approval. This icon can also be clicked when you want to view any friend recommendations or search for friends on Facebook.

Messages - This section allows you to send and receive private messages between one or more of your friends.

Notifications - Any time a friend or Facebook application creates a new post you'll be notified in this section. Clicking this icon shows all recent notifications. To change notifications including any Facebook applications or games click the See All Notifications link at the bottom and check or uncheck what you want to be notified on.

Search - Finally, the search box in Facebook can be a powerful tool that can be used to quickly find any current friends or people on Facebook. Also, searching for terms such as a company name, product, sports team, music band, etc. will find fan pages and groups that can be joined.

• Modify your account notifications

Keep your e-mail and your cell phone clean by updating or eliminate Facebook notifications or keep more up-to-date by adding new notifications. Facebook notifications can be added and removed by clicking Account link in the top right corner, thenAccount Settings, and then clicking the Notifications tab.

• Top News and Most Recent

By default Facebook displays your wall postings in the News format, which means it only displays posts it believes are most relevant to you. These results are based on your past interaction with your friends. If you want to see every post made by all your friends that are not hidden click the Most recent link in the upper right section of your news feed as shown in the above picture example.

If you want to adjust who shows up manually click the Edit Options in the bottom right corner of your news feed.

• View High School work friends

If you've added your High School or previous Work locations to your profile, quickly see all classmates and co-workers on Facebook by clicking the link in your Info tab under your profile.

• Quickly change profile picture

Your profile picture can be changed by visiting your profile, hovering the mouse over your current profile picture, and clicking the Change Picture link in the top right corner.

• Don't post private information on friend's walls on in comments

When you make a post on a friend's wall or in any of their comments realize that any of their friends are going to be able to see that post. If you want for something to remain only between you and a friend send them a Facebook message instead.

• Suggestions and random friend invites

As you get more friends on Facebook it will begin making friend, groups, and fan suggestions. These are suggestions made by Facebook and not your friends. Unless these are something you're interested in they can be ignored.

This same rule can be applied to people who may want to be your friend that you don't know. If you don't know someone don't accept his or her friend invite. Once someone becomes your friend they'll have access to any information your friends are capable of seeing.

• Tag your Facebook friends in your photos

Always make sure to tag any of your Facebook friends that are in pictures you upload. However, never tag someone who is not in the picture. When someone is tagged in a photo that picture is automatically added to that persons profile and is a great way to share pictures with all friends.

Top 10 keyboard shortcuts everyone should know

Using keyboard shortcuts can greatly increase your productivity, reduce repetitive strain, and help keep you focused. For example, to copy text, you can highlight text and press the Ctrl + C shortcut. The shortcut is faster than moving your hands from the keyboard, highlighting with the mouse, choosing copy from the file menu, and then returning to the keyboard.

Below are the top 10 keyboard shortcuts we recommend everyone memorize and use.

• Ctrl + C or Ctrl + Insert and Ctrl + X

Both Ctrl + C and Ctrl + Insert will copy the highlighted text or selected item. If you want to cut instead of copy press Ctrl + X.

• Ctrl + V or Shift + Insert

Both the Ctrl + V and Shift + Insert will paste the text or object that's in the clipboard.

Use the above text input fields to highlight the "Cut or copy this text" text and press either Ctrl + C to copy or Ctrl + X to Cut the text. Once Cut Move to the next field and press Ctrl + V or Shift + Insert to paste the text.

• Ctrl + Z and Ctrl + Y

Pressing Ctrl + Z will Undo any change. For example, if you cut text, pressing this will undo it. These shortcuts can also be pressed multiple times to undo or redo multiple changes. Pressing Ctrl + Y would redo the undo.

Use the above text input field to highlight some or all of the text and then press Ctrl + X to cut the text. Once the text has disappeared press the Ctrl + Z to undo the cut.

Tip: If you did the first example as well (cut and paste text) if you continue to press Ctrl + Z it is also going to undo that change.

• Ctrl + F

Pressing Ctrl + F opens the Find in any program. Ctrl + F includes your Internet browserto find text on the current page. Press Ctrl + F now to open the Find in your browser and search for "shortcut" to find each time shortcut is mentioned on this page.

• Alt + Tab or Ctrl + Tab

Pressing Alt + Tab switches between open programs moving forward. For example, if you have your browser window open and other programs running in the background press and hold Alt and then press tab to cycle through each open program.

Tip: Press Ctrl + Tab to switch between tabs in a program. For example, if you have multiple tabs open in your browser now press Ctrl + Tab to switch between open tabs.

Tip: Adding the Shift key to Alt + Tab or Ctrl + Tab moves backward. For example, if you are pressing Alt + Tab and pass the program you want to use, press Alt + Shift + Tab to move back to that program.

Tip: Windows Vista and 7 users can also press the Windows Key + Tab to switch through open programs in a full screenshot of the window.

• Ctrl + Back space and Ctrl + Left or Right arrow

Pressing Ctrl + Backspace will delete a full word at a time instead of a single character.

Holding down the Ctrl key while pressing the left or right arrow will move the cursor one word at a time instead of one character at a time. If you want to highlight one word at a time, hold down Ctrl + Shift and then press the left or right arrow key to move one word at a time in that direction while highlighting each word.

• Ctrl + S

While working on a document or other file in almost every program, pressing Ctrl + Ssaves that file. Use this shortcut key frequently if you're working on anything important in case an error happens, you lose power, or other problem that causes you to lose any work since the last save.

• Ctrl + Home or Ctrl + End

Ctrl + Home will move the cursor to the beginning of the document, and Ctrl + End will move the cursor to the end of a document. These shortcuts work with most documents, as well as web pages.

• Ctrl + P

Open a print preview of the current page or document being viewed. For example, pressCtrl + P now to view a print preview of this page.

• Page Up, Spacebar, and Page Down

Pressing either the page up or page down key will move that page one page at a time in that direction. When browsing the Internet, pressing the spacebar also moves the page down one page at a time.

Tip: If you are using the spacebar to go down one page at a time, press the Shift key and spacebar to go up one page at a time.
