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, highlighting text with the keyboard and pressing Ctrl + C is much faster than taking your hand from the keyboard, highlighting the text using the mouse, clicking copy from the file menu, and then putting your hand back in place on the keyboard. Below are our top 10 keyboard shortcuts we recommend everyone memorize and use.

Ctrl + C or Ctrl + Insert

Both Ctrl + C and Ctrl + Insert will copy the highlighted text or selected item.

Ctrl + V or Shift + Insert

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

Ctrl + Z and Ctrl + Y

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

Ctrl + F

Pressing Ctrl + F opens the Find in any program. This includes your Internet browser to find text on the current page.

Alt + Tab or Ctrl + Tab

Quickly switch between open programs moving forward.

Tip: Press Ctrl + Tab to switch between tabs in a program.

Tip: Adding the Shift key to Alt + Tab or Ctrl + Tab will move backwards. For example, if you are pressing Alt + Tab and pass the program you want to switch to, press Alt + Shift + Tab to move backwards 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 wanted to highlight one word at a time you can 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. This shortcut key should be used frequently anytime you're working on anything important.

Ctrl + Home or Ctrl + End

Ctrl + Home will move the cursor to the beginning of the document and Ctrl + Endwill move the cursor to the end of a document.

Ctrl + P

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

Page Up, Space bar, 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 space bar also moves the page down one page at a time.

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

How do I remove computer memory in my computer?

If memory is already installed in your computer memory slots, some or all of it needs to be removed before additional memory can be added. Below are the steps on how to remove memory from your computer.

If the computer is not already opened, open the computer and locate the memory in the memory slots you want to remove.

If all your memory slots are occupied and you are not sure what memory to remove, use a third-party tool such as the onlineCrucial Memory scanner to display your memory information. The picture is an example of what the results of this memory scanner may show. As can be seen in the picture, the example computer has 8GB of memory with 2GB memory cards in each of the available slots. If you wanted to upgrade this to a total of 16GB of memory, you would remove all 2GB memory sticks and replace them with 4GB memory modules.

Once you've located the memory you want to remove from the computer you should notice two tabs on either side of the memory slot as shown in the picture below. Press each tab down and away from the memory slot. If done successfully, the memory should pop out and once both tabs are away from the memory module you can lift the memory out with no effort.

Installing a PC computer power supply

Before getting started

1. Write down important information from the top or bottom of the power supply such as the Model Number, Serial Number and specifications (such as voltage...).
2. Ensure you are familiar with ESD and its potential dangers.
3. When physically installing the power supply, ensure the computer is off and the power plug is disconnected from the power supply.

Remove previous power supply

If you are replacing a power supply that is already in the computer, remove the power supply from the computer by first disconnecting the power supply from the motherboard and all other devices and then unscrewing the screws on the back of the power supply and possibly within the computer case.

Install power supply

Once no power supply is installed into the computer, place the new power supply into the computer and screw the screws into the back of the power supply. Most computer cases today also have a screw within the computer case; if present, also screw a screw into this hole.

Connect cables

Once the power supply has been physically installed into the case and is being held in the case, attach the power supply cable from the power supply to the motherboard. Next, connect each of the power connectors for the hard drive, cd drive, floppy drive and any other peripherals.
