Position the mouse pointer on a button and a _____ displays with information about the button.
The text you type appears wherever the insertion/cursor point is positioned in the current document. Moving the insertion point around the screen is a critical part of creating and editing documents. To move the insertion point around the screen, you can use either the keyboard or the mouse. Table 1-1 lists ways to move the insertion point by using keystrokes. For more on Microsoft Word classes in Los Angeles call us on 888.815.0604. To use the mouse to move the insertion point, first position the desired section of text in the document window by using the scroll bars. Then, position the mouse pointer in the desired location and click the left mouse button. If you are using a Microsoft IntelliMouse, you can display and move the insertion point to a different part of the document by using the wheel button. Do not use the Enter key to move the insertion point unless you want to add hard returns, or blank lines, to your document. If, however, you want to move the insertion point to an area of your document into which you have not yet entered text, you need to press the Enter key until the insertion point is positioned in the desired location.
Table 1-1: Moving the Insertion Point by Using Keystrokes You can also use Word’s Find feature to help you move the insertion point. Instead of scrolling or paging through the document to find occurrences of specific text, you can have Word perform the search by defining the desired text on the Find and Replace dialog box’s Find tab. Figure 1-4 illustrates the Find tab. Finding is not limited to letters and numbers; you can search for a phrase, including punctuation and spaces, as well. When Word finds the desired text in the document, it highlights the text, suspends the search, and leaves the Find and Replace dialog box open. You can then place the insertion point at the found text, move to the next occurrence of the text, or end the search. If the text cannot be found in the current document, Word displays a message box indicating the text does not appear in the document. In Word 2013 the find option also activates the Navigation Pane to search within a documents. The Replace option helps to replace the particular word selected or it changes the particular word throughout the document. This feature saves our time in searching the word and replacing one by one.

In computer user interfaces, a cursor is an indicator used to show the current position for user interaction on a computer monitor or other display device that will respond to input from a text input or pointing device. The mouse cursor is also called a pointer,[1] owing to its resemblance in usage to a pointing stick.
Cursor is Latin for 'runner'. A cursor is a name given to the transparent slide engraved with a hairline used to mark a point on a slide rule. The term was then transferred to computers through analogy. On 14 November 1963, while attending a conference on computer graphics in Reno, Nevada, Douglas Engelbart of Augmentation Research Center (ARC) first expressed his thoughts to pursue his objective of developing both hardware and software computer technology to "augment" human intelligence by pondering how to adapt the underlying principles of the planimeter to inputting X- and Y-coordinate data, and envisioned something like the cursor of a mouse he initially called a "bug", which, in a "3-point" form, could have a "drop point and 2 orthogonal wheels".[2] He wrote that the "bug" would be "easier" and "more natural" to use, and unlike a stylus, it would stay still when let go, which meant it would be "much better for coordination with the keyboard."[2] According to Roger Bates, a young hardware designer at ARC under Bill English, the cursor on the screen was for some unknown reason also referred to as "CAT" at the time, which led to calling the new pointing device a "mouse" as well.[3][4] Further information: Caret navigation See also: Text field The cursor for the Windows Command Prompt (appearing as an underscore at the end of the line) In most command-line interfaces or text editors, the text cursor, also known as a caret,[5] is an underscore, a solid rectangle, or a vertical line, which may be flashing or steady, indicating where text will be placed when entered (the insertion point). In text mode displays, it was not possible to show a vertical bar between characters to show where the new text would be inserted, so an underscore or block cursor was used instead. In situations where a block was used, the block was usually created by inverting the pixels of the character using the boolean math exclusive or function.[6] On text editors and word processors of modern design on bitmapped displays, the vertical bar is typically used instead. In a typical text editing application, the cursor can be moved by pressing various keys. These include the four arrow keys, the Page Up and Page Down keys, the Home key, the End key, and various key combinations involving a modifier key such as the Control key. The position of the cursor also may be changed by moving the mouse pointer to a different location in the document and clicking. The blinking of the text cursor is usually temporarily suspended when it is being moved; otherwise, the cursor may change position when it is not visible, making its location difficult to follow. The concept of a blinking cursor can be attributed to Charles Kiesling Sr. via US Patent 3531796,[7][8] filed in August 1967.[9] Some interfaces use an underscore or thin vertical bar to indicate that the user is in insert mode, a mode where text will be inserted in the middle of the existing text, and a larger block to indicate that the user is in overtype mode, where inserted text will overwrite existing text. In this way, a block cursor may be seen as a piece of selected text one character wide, since typing will replace the text "in" the cursor with the new text. Bi-directional textA vertical line text cursor with a small left-pointing or right-pointing appendage is for indicating the direction of text flow on systems that support bi-directional text, and is thus usually known among programmers as a 'bidi cursor'. In some cases, the cursor may split into two parts, each indicating where left-to-right and right-to-left text would be inserted.[10] The common cursor roles for a cursor set. Common pointer types (enlarged) In computing, a pointer or mouse cursor (as part of a personal computer WIMP style of interaction)[11][12][13] is a symbol or graphical image on the computer monitor or other display device that echoes movements of the pointing device, commonly a mouse, touchpad, or stylus pen. It signals the point where actions of the user take place. It can be used in text-based or graphical user interfaces to select and move other elements. It is distinct from the cursor, which responds to keyboard input. The cursor may also be repositioned using the pointer. The pointer commonly appears as an angled arrow (angled because historically that improved appearance on low-resolution screens[14]), but it can vary within different programs or operating systems. The use of a pointer is employed when the input method, or pointing device, is a device that can move fluidly across a screen and select or highlight objects on the screen. In GUIs where the input method relies on hard keys, such as the five-way key on many mobile phones, there is no pointer employed, and instead, the GUI relies on a clear focus state. The pointer or mouse cursor echoes movements of the pointing device, commonly a mouse, touchpad or trackball. This kind of cursor is used to manipulate elements of graphical user interfaces such as menus, buttons, scrollbars or any other widget. It may be called a "mouse pointer" because the mouse is the dominant type of pointing device used with desktop computers. AppearanceA wait cursor replaces the pointer with an hourglass. The pointer hotspot is the active pixel of the pointer, used to target a click or drag. The hotspot is normally along the pointer edges or in its center, though it may reside at any location in the pointer.[15][16] In many GUIs, moving the pointer around the screen may reveal other screen hotspots as the pointer changes shape depending on the circumstances. For example:
I-beam pointerThe I-beam pointer. The I-beam pointer (also called the I-cursor) is a cursor shaped like a serifed capital letter "I". The purpose of this cursor is to indicate that the text beneath the cursor can be highlighted and sometimes inserted or changed.[19] Pointer trails and animationAn example of mouse pointer trails. Pointer trails can be used to enhance its visibility during movement. Pointer trails are a feature of GUI operating systems to enhance the visibility of the pointer. Although disabled by default, pointer trails have been an option in every version of Microsoft Windows since Windows 3.1x. When pointer trails are active and the mouse or stylus is moved, the system waits a moment before removing the pointer image from the old location on the screen. A copy of the pointer persists at every point that the pointer has visited at that moment, resulting in a snake-like trail of pointer icons that follow the actual pointer. When the user stops moving the mouse or removes the stylus from the screen, the trails disappear and the pointer returns to normal. Pointer trails have been provided as a feature mainly for users with poor vision and for screens where low visibility may become an issue, such as LCD screens in bright sunlight. In Windows, pointer trails may be enabled in the Control Panel, usually under the Mouse applet. Introduced with Windows NT, an animated pointer was a small looping animation that was played at the location of the pointer.[20] This is used, for example, to provide a visual cue that the computer is busy with a task.[21] After their introduction, many animated pointers became available for download from third party suppliers. Unfortunately, animated pointers are not without their problems. In addition to imposing a small additional load on the CPU, the animated pointer routines did introduce a security vulnerability. A client-side exploit known as the Windows Animated Cursor Remote Code Execution Vulnerability used a buffer overflow vulnerability to load malicious code via the animated cursor load routine of Windows.[22] EditorA pointer editor is software for creating and editing static or animated mouse pointers. Pointer editors usually support both static and animated mouse cursors, but there are exceptions. An animated cursor is a sequence of static cursors representing individual frames of an animation. A pointer editor should be able to:
Pointer editors are occasionally combined with icon editors because computer icons and cursors share similar properties. Both contain small raster images and the file format used to store icons and static cursors in Microsoft Windows is similar. Despite the similarities, pointer editors differ from icon editors in several ways. While icons contain multiple images with different sizes and color depths, static cursors (for Windows) only contain a single image. Pointer editors must provide the means to set the hot spot. Animated pointer editors additionally must be able to handle animations. An example of a 3D cursor in a 3D modeling environment (center). The idea of a cursor being used as a marker or insertion point for new data or transformations, such as rotation, can be extended to a 3D modeling environment. Blender, for instance, uses a 3D cursor to determine where operations such as placing meshes are to take place in the 3D viewport.[23]
