The bar you see on the rightmost corner of almost every application, is what we call a “scroll bar”. The scroll bar, previous called a “handle”, is an object we see on GUIs (graphical user interface) that help users move the application window up or down if the content has continuous text or pictures. In computing terms, you can basically call the scroll bar your “thumb” because this is what you use to browse the pages of your documents, much like how you would thumb through the pages of a book.
The scroll bar is composed of three parts and they are the following.
- Thumb. Also called scroller, knob, elevator, scroll box, quint, puck, scroll thumb, wiper or grip, the thumb is a box with square or rounded corners that you to move window contents up or down. All you have to do is drag it up or down and the material you have on screen will move accordingly to your wishes.
- Scroll Bar. The scroll bar serves as the thumb’s pathway where it can move up or down.
- Scroll Arrows. On both ends of the scroll bar, you will see two scroll arrows; an arrow pointing upwards and the other, pointing downwards.
So how do you go about moving the scroll bar on your computer? Ideally speaking, dragging the thumb up or down is the way to move it but you can use different ways on how to move it, depending on your need. The following lists the ways of how you can move the scroll bar on your computer screen.
- Using your mouse, click the scroll arrows up or down. You can use these arrows to move the window one line at a time. If you hit the down scroll arrow, the page will move only a line downwards. If you hit the up scroll arrow, the page will move only a line upwards this time.
- Using your keyboard, continuously depress the up or down scroll arrow. This still has the same effect as the first way, but the difference would be that your content is moving one line at a time, but at a more rapid pace.
- Using your mouse, click anywhere within the scroll bar. If you click the space below the thumb, your screen will move one page downwards. If you click the space above the thumb, your screen will move one page upwards.
- Using your keyboard, press the “up” or “down” arrows. The up or down arrows will move your content one line at a time.
- Using your keyboard, press the “Ctrl” and “Page Up” or “Page Down” keys. Doing so will move your content one page upwards or downwards.
Doing one of the stated ways above on how to move the scroll bar on a computer is helpful but you also have to consider if your mouse has the scroll wheel. It would be a lot easier for you to employ the use of the scroll wheel in moving the contents up or down on your monitor. Notice that if you use your scroll wheel, that the scroll bar is also moving accordingly.
