Definition
A cursor is a visual indicator on a computer display that shows where the next character to be typed will appear or where user interaction will take place. Typically, cursors appear as blinking underscores, vertical bars, or rectangles.
Examples
- Text Cursor: In a word processor, the cursor may be a vertical blinking bar indicating where the next text character will appear.
- Pointer Cursor: When using a computer mouse, the cursor changes to a pointing arrow to indicate where clicks will be registered.
- Loading Cursor: Appears as a spinning circle or hourglass, indicating that the system is processing a task and is temporarily unresponsive.
- Insert Cursor: In text editing programs, this cursor can switch between ‘insert’ mode (a vertical bar) and ‘overwrite’ mode (a filled rectangle).
Frequently Asked Questions (FAQs)
What is a text cursor?
The text cursor, often known as a caret, shows where the next character you type will appear in a text field or document.
Why does my cursor keep blinking?
The cursor blinks to make it easy to locate your text insertion point on the screen. This blinking is a user interface design choice to attract attention and indicate readiness for input.
Can I change the appearance of my cursor?
Yes, many operating systems and software applications allow users to customize their cursor’s appearance, including changing its shape, size, and color.
What does a loading cursor mean?
A loading cursor, such as a spinning wheel or hourglass, indicates that the computer is busy processing a task, and the system might be unresponsive for a short period.
How do I move the cursor in a text document?
You can move the cursor using the arrow keys on the keyboard, clicking a specific position with a mouse, or using touch gestures on a touchscreen device.
Related Terms
- Caret: Another term for the text cursor, usually represented as a vertical blinking bar.
- Pointer: The symbol (usually an arrow) controlled by the mouse or trackpad to interact with interface elements on the screen.
- Focus: The current area where user input will be directed, often indicated by the presence of a cursor.
- Insertion Point: The specific location in a text where new characters will appear, marked by the cursor.
