The primary means of using the clipboard consists of putting
information in it. One of the ways you do this is to copy information from a
source. To do this, you must first select that information and this depends on
what you are using. The document from which you are copying an item is referred
to as source.
To get text from a text-based application, first select it.
To copy it, most applications have a menu called Copy under Edit.
As mentioned above, copying consists of putting information
into the clipboard. To use that information, you must retrieve it from the
clipboard and put it where you want. This operation is referred to as pasting.
The document into which you are pasting an item is referred to as destination.
Before pasting something, you should first make sure that
the clipboard is not empty and, most of the time, you should know what is in the
clipboard. Remember that when the computer starts, the clipboard is empty. Also,
you have no way of visually
We mentioned that the clipboard could contain just about
anything: a character, a picture, a book, a group of pictures, a whole library,
a paragraph of text, an icon. Notice that these are disparate items that may not
share anything at all, except that they are retrieved from the computer. To
distinguish these items, the computer (the operating system) categorized using a
technique referred to as format. Because of the differences among these items,
each uses a specific format. Based on this, some items are categorized as text.
Some items are categorized as images (bitmap), and so on.
To paste the content of the clipboard, most applications
have a Paste item under their Edit menu. In most applications also, you can
right-click the area or section where you want to paste. The context menu would
have a Paste item. In both cases (using the main menu or the context menu), if
you click Paste, the contents of the clipboard would be added to that section.
As mentioned already, not all items use the same format. For
this reason, not just anything can be pasted in just anywhere. A text-based item
such as a letter, a symbol, a word, a sentence, a paragraph, a book (as text)
can be pasted in a document that can receive it. On the other hand, a picture
cannot be pasted in a text-based application like Notepad because the format is
not compatible. Some other applications (OLE-based, don't ask) can be pasted
almost anything, even a whole object from an application that has nothing to do
with the destination.
We mentioned that you could copy an item and put it in the
clipboard. When you do this, the item is only copied; in other words, a copy of
the item stays in the source and a copy is made in the clipboard. If you want to
remove an item from a source and have it only in the destination, you can Cut
it. When this is done, the item is deleted from the source.
To cut an item, most applications have a Cut item under the
Edit category of their main menu. They may also have a Cut item in their context
menu that appears when you right-click. Different applications handle cutting
differently. In most applications, once you click Cut, the character, word,
sentence, paragraph, the whole text, the picture, the group of pictures, etc, is
immediately deleted and put into the clipboard. With some other applications,
the item that was cut becomes dimmed or disabled but not completely deleted.
After cutting an item and pasting, it becomes available in
the destination. As stated already, if the destination is not equipped to
received the contents of the clipboard because of a different format, the
contents would not be pasted and nothing would happen. You would not even
receive a message stating that the pasting operation failed.

Practical Learning: Cutting and Pasting From the Clipboard |
|
Text Processing
|
Introduction
|
Text processing consists of adding characters,
inserting characters, moving characters, removing characters, adding empty spaces,
inserting empty spaces, removing empty spaces, adding words, inserting
words, moving words, removing words, adding paragraphs, inserting
paragraphs, or removing paragraphs. Advanced text processing can also
consist of adding pages, inserting pages, moving pages, or removing pages.
There are two broad types of text you will work on
when performing the operations related to text processing. Simple, or also
referred to as ASCII, text is a category that includes basic types of
characters recognized by the alphabet. The other category is referred to
as rich text. This involves fancy techniques of presenting text. Such text
can have different colors, the characters can have different sizes, and
the paragraphs can have different alignments.
Although there are various applications you can use to
perform text processing, they share many characteristics. Therefore, here
we will learn techniques that can be applied on almost any document,
regardless of the application
|
Text Processing and Characters
|
Character addition usually consists of adding a
character at the end of a word. Normally, this means that you would type a
new character to the right side of an existing word. Character inserting
consists of entering a new character anywhere inside of a word. Character
deletion consists of removing an existing character from text.
|
Text Processing and Words
|
Word addition consists of adding a word at the end of
a paragraph but before the last period. Word insertion consists of adding
a new word somewhere inside of a paragraph.
|
Text Processing and Paragraphs
|
Paragraph addition consists of adding a new paragraph
at the end of the document. Paragraph insertion consists of creating a new
paragraph somewhere inside of the document. The new paragraph can be made
of text or you may be asked to create an empty space between two
paragraphs.
