70 Things Every Computer Geek Should Know

The term ‘geek’, once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field. A geek is one who isn’t satisfied knowing only the surface facts, but instead has a visceral desire to learn everything possible about a particular subject.
A techie geek is usually one who knows a little about everything, and is thus the person family and friends turn to whenever they have a question. If you’re that type of person and are looking for a few extra skills to pick up, or if you’re a newbie aiming to get a handhold on the honor that is geekhood, read on to find out what skills you need to know.

26 Keyboard Shortcuts To Memorize Today

26 Shortcut Keys To Know by Heart 

 

Using a mouse is useful, but using a mouse and keyboard together can be much more efficient. Want to be a power user? The most efficient people know that tapping the right keys is much faster than maneuvering the mouse, and boosts productivity immensely. Here are 26 keyboard shortcuts that will save you time and energy, if you remember to use them.
A note: some of the shortcuts listed here work with all major operating systems (Windows, Mac OS X, or Linux). But some of them work only within...

Shift+Left

You can drag the cursor over text to select it. But using the keyboard can be much faster.
Press Shift+Left when in a text box, and the computer will select the character to the left of where you're typing. If you've already selected some text, this shortcut key simply adds the character to your current selection.
(The shortcut should work on Linux. On the Mac OS X, replace Shift with Alt.)

Shift+Right

Shift+Right works the same way as Shift+Left, except it selects the character to the right of the cursor.
(The shortcut should work on Linux. On the Mac OS X, replace Shift with Alt.)

Shift+Home

Shift+Home selects all text from the cursor to the start of the line. This is a quick way to select an entire line of text for cutting, copying, etc.
(The shortcut should work on Linux. On the Mac OS X, replace Shift with Alt.

Shift+End

Shift+End is Shift+Home's complement. It selects all text from the cursor to the end of the line. This is also a great way to select blocks of text for manipulation.
(The shortcut should work on Linux. On the Mac OS X, replace Shift with Alt.)

Ctrl+C

Computers do a splendid job of manipulating text, which makes editing a breeze—and plagiarism commonplace.
Ctrl+C Copies your selection to the clipboard. The clipboard acts a temporary repository that allows computer users to quickly move or duplicate text, pictures, or even music and video. As a general rule, the clipboard can only contain one item at a time.

Ctrl+V

Ctrl+V pastes the clipboard's contents into whatever you're editing. This shortcut will only work if you're trying to paste something that's compatible with the app you're using. Try pasting a picture into Windows Notepad for instance, and nothing will happen.
(Also works on Linux. For Mac OS X however, press the Command key (⌘) instead of Ctrl)

Ctrl+X

Ctrl+X "cuts" your selection. It works like Ctrl+C, but deletes the selection after transferring it to the clipboard.
(Also works on Linux. For Mac OS X however, press the Command key (⌘) instead of Ctrl)

Ctrl+F

Ctrl+F works with text. You use it to find a particular word or phrase. The more specific you are, the faster the search will be.
(Also works on Linux. For Mac OS X however, press the Command key (⌘) instead of Ctrl)

Ctrl+H

Ctrl+H also works with text. The command lets you replace all instances of a specific word or phrase with another one. Great for replacing names if you're sending the same letter or email to someone else.
(Also works on Linux. For Mac OS X however, press the Command key (⌘) instead of Ctrl)

Windows+Left

Hold the Windows key down while pressing any of the four arrow keys to arrange windows quickly.
Windows+Left - Quickly resize a window so that it only takes up half of your screen (length-wise), then snaps it to the left. This is very useful for arranging apps side by side, but only works for resizable windows. Pressing this shortcut again snaps the window to the right, while another press restores the window to its "old" size.
(Windows 7 only)
