But You're My Favorite!

I throw a little too much love towards Mozilla Firefox, so today I'm going to include some Internet Explorer goodness to try and balance stuff out. So, let's talk a little bit about favorites, shall we? Internet Explorer has something called the Favorites Center, where all of your most loved and cherished websites can be stored and accessed. Perhaps you knew about that already, eh? Great! That means that these Favorites Center shortcuts will add to your repertoire and your browsing prowess will be upgraded, indeed!

Give these a shot!

Ctrl + I – Open Favorites

Ctrl + Shift + I – Open Favorites in pinned mode

Ctrl + B – Organize Favorites

Ctrl + D – Add current page to Favorites

Ctrl + J – Open Feeds (For RSS Feeds)

Ctrl + Shift + J – Open Feeds in pinned mode

Ctrl + H – Open History

Ctrl + Shift + H – Open History in pinned mode

TAB Key Options!

Multi-tab browsing in Firefox makes managing multiple web pages a breeze! Remember how Ctrl + T opens a new tab? Well, what about Ctrl+ Page Up and Ctrl+Page Down to switch between those tabs? Want to navigate between tabs even faster? Check these out:

Ctrl+1: Switch to the first tab
Ctrl+2: Switch to the second tab
Ctrl+3: Switch to the third tab
Ctrl+4: Switch to the fourth tab
Ctrl+5: Switch to the fifth tab
Ctrl+6: Switch to the sixth tab
Ctrl+7: Switch to the seventh tab
Ctrl+8: Switch to the eighth tab
Ctrl+9: Switch to the LAST tab

Even if you've got a ridiculous amount of tabs open, Ctrl+9 will always go to the farthest tab on the right.

But what about Ctrl+0? Well, because you can switch the size of the font with Ctrl+= or Ctrl+-, there needs to be a way to set it all back to defaults, right? That's where Ctrl+0 comes in. Use it to put the text in Firefox back to normal.

Wonderful!

What the F-key? F1 through F4

See that line of keys ranging from F1 to F12 at the top of your keyboard? Wonder what all of 'em do? Yeah, so do I, and that's why today we're going to take a trip down funky f-key lane to discover the fun of Function Keys!

Function keys have many, many uses, some of which are specific to the program that's running at the time. They're mainly used as shortcuts or in conjunction with the CTRL, ALT, and Shift keys, which I'll get more into in another article.

For now, here are the basics of function keys F1 – F4.

F1- Typically pressing this brings up the help file for the program you're currently in. To test this, go ahead and left click on a blank area of your desktop, then press F1. The help file should spring to life, offering it's bounty of knowledge!

F2 – This F-key is used to rename stuff. Click on a file or folder and strike the F2 key; you'll be able to rename it with ease! This is a good one to know if you're zipping through a bunch of files you're archiving and you have a specific naming convention in mind. Click the file, press F2 and rename it! - wash, rinse, repeat!

F3 – Used to bring up the search function in Windows, but varies for other programs. Great for Internet Explorer and Firefox users who want to find a specific word or phrase on a web page with ease!

F4 – In Internet Explorer the F4 key opens the address bar. Even though I said I wouldn't be mentioning any extra key commands until later, I must mention that pressing ALT + F4 will close any active program. Careful with this one! :)

Wild Cards

When doing a search you can use an asterisk (*) in place of letters or numbers. This is called a "Wild Card" and it really comes in handy.

Let's say you're looking for a file that starts with "ran" but aren't sure what the rest of the name is. Just type in...

ran*

All files of any type that begin with "ran" will be found such as "randy.doc" or "rand-mcnally.exe".

Let's say you know that your file is a Word doc. Then type in "ran*.doc".

What if you're just not sure of the single character in a file name? Then use a Question Mark wild card...

ran?.doc



You could end up with "rant.doc", "rank.doc" or "ran1.doc" but not "randy.doc"

This not only works with Search/Find in Windows, but on many Internet search engines as well.

Excel Tip: Fast data entry

Suppose you want to put the same string, number, or formula into two or more cells. Using the old-fashioned approach, you’d type the string, number, or formula into the first cell and then copy and paste that entry into the destination cells. But there’s a little-known tip that makes short work of placing the same entry in multiple cells. First, select all the cells you want to populate. Type the entry, but don’t press Enter. Instead, press Ctrl + Enter. When you do, Excel will copy what you typed into all of the selected cells.

Excel Tip: Noncontiguous selections

You can select any cells you want, regardless of whether they’re next to each other in a row or column. Hold down the Ctrl key while you click on a cell or click and drag through a range of cells. As long as you hold down the Ctrl key, you can click and select to your heart’s content.

You can also use this in conjunction with the AutoCalculate function on Excel’s status bar to analyze any combination of individual cells or blocks of cells. Just select the values you want to analyze, right-click on the status bar, and choose the desired function to see the results

Excel Tip: Fast navigation

When you press Ctrl and any arrow key (north, east, south, or west), you jump to the last populated cell in that direction. Think of using the Ctrl-arrow key shortcut as an alternative to pressing Page Down to find the bottom row of a data set or pressing Tab to find the last column. Bonus tip: Hold down the Shift key while you press any Ctrl-arrow key shortcut to select all the cells between where you are and where you jump with the Ctrl key.

Copy Files and Folders to CD

To copy files and folders to a CD

•Insert a blank, writable CD into the CD recorder.

•Open My Computer.

•Click the files or folders you want to copy to the CD. To select more than one file, hold down the CTRL key while you click the files you want. Then, under File and Folder Tasks, click Copy this file, Copy this folder, or Copy the selected items.

•If the files are located in My Pictures, under Picture Tasks, click Copy to CD or Copy all items to CD, and then skip to step 5.

•In the Copy Items dialog box, click the CD recording drive, and then click Copy.

•In My Computer, double–click the CD recording drive. Windows displays a temporary area where the files are held before they are copied to the CD. Verify that the files and folders that you intend to copy to the CD appear under Files Ready to be Written to the CD.

•Under CD Writing Tasks, click Write these files to CD. Windows displays the CD Writing Wizard. Follow the instructions in the wizard.


Notes:

•Do not copy more files to the CD than it will hold. Standard CDs hold up to 650 megabytes (MB). High–capacity CDs hold up to 850 MB.

•Be sure that you have enough disk space on your hard disk to store the temporary files that are created during the CD writing process. For a standard CD, Windows reserves up to 700 MB of the available free space. For a high–capacity CD, Windows reserves up to 1 gigabyte (GB) of the available free space.

•After you copy files or folders to the CD, it is useful to view the CD to confirm that the files are copied. For more information, click Related Topics.
To stop the CD recorder from automatically ejecting the CD

•Open My Computer.


•Right–click the CD recording drive, and then click Properties.

•When you make a folder private, all of its subfolders are private as well. For example, when you make My Documents private, you also make My Music and My Pictures private. When you share a folder, you also share all of its subfolders unless you make them private.
•You cannot make your folders private if your drive is not formatted as NTFS For information about converting your drive to NTFS

Search For Hidden Or System Files In Windows XP

The Search companion in Windows XP searches for hidden and system files differently than in earlier versions of Windows. This guide describes how to search for hidden or system files in Windows XP.

Search for Hidden or System Files By default, the Search companion does not search for hidden or system files. Because of this, you may be unable to find files, even though they exist on the drive.

To search for hidden or system files in Windows XP:
Click Start, click Search, click All files and folders, and then click More advanced options.

Click to select the Search system folders and Search hidden files and folders check boxes.

NOTE: You do not need to configure your computer to show hidden files in the Folder Options dialog box in Windows Explorer to find files with either the hidden or system attributes, but you need to configure your computer not to hide protected operating system files to find files with both the hidden and system attributes. Search Companion shares the Hide protected operating system files option (which hides files with both the system and hidden attributes) with the Folder Options dialog box Windows Explorer.
