Text box in the context of Lightweight markup language

The arrow keys (↑ Up, ← Left, ↓ Down and → Right) are the four keys on a computer keyboard labelled with directional arrows, typically found in an inverted-T layout to the bottom-right of the keyboard and to the left of the numeric keypad. They are a subset of the cursor keys, which include others like the Home, End, and Page Up/Down keys.

The arrow keys have a wide variety of functions. In a command-line interface (CLI), text box, or word processor, they typically enable caret navigation, allowing the user to move the text cursor between characters and lines. Meanwhile, in graphical user interfaces (GUIs), file viewers, and web browsers, the keys are generally used for scrolling, providing an alternative to dragging a scrollbar with a mouse pointer. Specific kinds of software make use of the arrow keys in more unique ways: they are used in most media player software to skip backward or forward through audio and video files, and they are used in some video games to move a player character around a virtual space (although modern games typically use the WASD keys for this purpose).

An online rich-text editor is the interface for editing rich text within web browsers, which presents the user with a "what-you-see-is-what-you-get" (WYSIWYG) editing area. The aim is to reduce the effort for users trying to express their formatting directly as valid HTML markup.

Though very early browsers could display rich text, user data entry was limited to text boxes with a single font and style (implemented with the <textarea> HTML element). Internet Explorer was the first to add a special "designMode" which allowed formatted parts of a document to be edited by the user using a cursor. Mozilla followed suit in version 1.3, and most major browsers now implement this informal standard in some capacity.

A search suggest drop-down list is a query feature used in computing to show the searcher shortcuts, while the query is typed into a text box. Before the query is complete, a drop-down list with the suggested completions appears to provide options to select. The suggested queries then enable the searcher to complete the required search quickly. As a form of autocompletion, the suggestion list is distinct from search history in that it attempts to be predictive even when the user is searching for the first time. Data may come from popular searches, sponsors, geographic location or other sources. These lists are used by operating systems, web browsers and various websites, particularly search engines. Search suggestions are common with a 2014 survey finding that over 80% of e-commerce websites included them.

The computing science of syntax and algorithms are used to form search results from a database. Content management systems and frequent searches can assist software engineers in optimizing more refined queries with methods of parameters and subroutines. Suggestions can be results for the current query or related queries by words, time and dates, categories and tags. The suggestion list may be reordered by other options, as enumerative, hierarchical or faceted.

A search box, search field or search bar is a graphical control element used in computer programs, such as file managers or web browsers, and on web sites. A search box is usually a single-line text box or search icon (which will transform into a search box on click activity) with the dedicated function of accepting user input to be searched for in a database. Search boxes on web pages are usually used to allow users to enter a query to be submitted to a Web search engine server-side script, where an index database is queried for entries that contain one or more of the user's keyword research.

Search boxes are commonly accompanied by a search button (sometimes indicated only by a magnifying glass symbol) to submit the search. However, the search button may be omitted as the user may press the enter key to submit the search, or the search may be sent automatically to present the user with real-time results.
