Scroll arrows pointed inwards in the direction the content would move based on user studies, and + and – buttons allowed for scrolling by pages. īetween 19, the Xerox Star moved the scrollbar to the right to get it out of the way and reduce visual clutter. The left button scrolled up to move the selected position to the top edge of the window, and the right button scrolled down to move the top edge of the window to the selected position. The bar's shaded thumb showed the percentage of content visible and was controlled by the middle button.
In 1980, Interlisp had a scrollbar that appeared on the left side of the window as the cursor moved towards the left. The center thumb of the bar could be dragged smoothly and showed the percentage of the content visible the first proportional scroll bar.
Clicking at the right half of the scrollbar moved the content up, and the left half moved the content down. In 1977, Smalltalk included a stable scrollbar on the left side of the focus window. Holding down the middle yellow button changed the cursor to a thumb, allowing for jumping to that percentage of the document with an indicator of current placement. Pressing the right or bottom blue button scrolled the content down, and the line at the top of the window went down to the cursor. Pressing the left or top red button scrolled the content up, and the line next to the cursor went to the top of the window. In 1974, moving the cursor to the left margin while using Bravo changed its shape to a double-headed arrow to allow for scrolling.

The “thumb” has different names in different environments: on the Mac OS X 10.4 it is called a "scroller" on the Java platform it is called "thumb" or "knob" Microsoft's. Two arrows are often included on either end of the thumb or trough for more precise adjustments. This can be placed vertically, horizontally, or both in the window depending on which direction the content extends past its boundaries. Īlthough scrollbar designs differ throughout their history, they usually appear on one or two sides of the viewing area as long rectangular areas containing a bar (or thumb) that can be dragged along a trough (or track) to move the body of the document.

Examples of horizontal and vertical scrollbars around a text boxĪ scrollbar is an interaction technique or widget in which continuous text, pictures, or any other content can be scrolled in a predetermined direction (up, down, left, or right) on a computer display, window, or viewport so that all of the content can be viewed, even if only a fraction of the content can be seen on a device's screen at one time.
