Email address formats: RIGHT or wrong?

Q. Is it true that all email addresses have to be in lower case or can they be in upper case, too?

A. To answer this thoroughly -- and would you expect anything less? -- we need to take a look at the history of email addresses. Back in the primordial Internet era, when the Unix operating system ruled the land, all commands, names, paths and directories were in lower case, as were all email addresses. As the Internet blossomed, upper and lower case letters began to appear, which generally worked quite well, though there were exceptions.

Today, the Internet email mail system is much more sophisticated technologically than it was years ago, so it really doesn’t matter if an email address is upper case, lower case or a combination, though lower case or upper and lower case is generally easier for human eyes to read.

Q. I read one of your columns in which you mentioned copying and pasting. I’m a new user, but I don’t know how to copy and paste. Could you explain that? Your weekly newsletter is very helpful. I’m happy I found you.

A. It’s equally nice to be found, thank you. Copying and pasting are important skills for any computer user, so let’s run through the basics: In order to copy text, you first need to select (highlight) the text to be copied. There are several ways to accomplish this, but my preferred method is to hold down the left mouse button and slowly move the cursor to the end of the text you want to copy. When the text is highlighted, release the mouse button.

Another way to select text is to single-click your left mouse button at the beginning of the text, hold down the SHIFT key and click once at the end of the text. Everything between the first click and the second click will be highlighted, or what we in the biz called clickified. (Not really.)

A third way to select text (as if two choices aren’t enough) is a variation of the second method and involves using the arrow keys to move the cursor to the beginning of your text, then holding down the SHIFT key while using the arrow keys to move to the end of your text.

To copy the highlighted text, right-click and select COPY from the menu that appears. Alternatively, you can press the keystroke combination CTRL + C. It will appear as if nothing happened, but you will have copied your text to the Windows Clipboard where it will await your pasting command.

To paste, click once where you want the text to appear, then either right-click and select PASTE, or using your keyboard, press CTRL + V, which begs the question, if CTRL + C is the COPY command, why isn’t CTRL + P the PASTE command? (CTRL + P is the Print command.) Here’s an easy way to remember: Think of pasting in terms of putting the text vhere you vant it to appear, and you’ll never forget CTRL + V. (You’re velcome!)
