Pronunciation: [tˈab ˈɔːdə] (IPA) 
The spelling of the word "tab order" is fairly straightforward. "Tab" is pronounced /tæb/ phonetically, utilizing the "t" sound followed by a short "a" sound and rounded out with a hard "b." "Order" is pronounced /ˈɔrdər/, featuring a soft "o" sound, the "r" sound, and an "er" sound at the end. Together, these phonetic sounds form the word "tab order," referring to the arrangement of tabs on a computer screen or in a document.
Tab order refers to the specific sequence in which the focus moves between interactive elements or fields on a digital platform or software program. It determines the order in which elements receive focus when a user navigates through the content using the "tab" key on a keyboard. The tab key is commonly used to jump between different focusable elements such as buttons, links, input fields, and interactive controls on a webpage or within an application.
The tab order is an essential accessibility feature that ensures users with disabilities or those who prefer keyboard navigation can easily interact with the content. It allows them to traverse through different sections or options without needing to rely solely on a mouse or touchscreen.
In most cases, the tab order follows a logical flow, moving from left to right and top to bottom, resembling reading patterns. However, it can be customized to suit specific preferences or design requirements. Developers or designers typically define the tab order manually by specifying the order of focusable elements in the source code or using visual design tools.
Having a well-organized tab order enhances the user experience, enabling efficient navigation and reducing frustration. It helps users quickly locate and interact with the desired elements and ensures a smooth and accessible interaction for all users, regardless of their physical abilities or input devices.
The word "tab order" has a relatively straightforward etymology.
The term "tab" originated from the use of typewriters, specifically the tab key located on the keyboard. This key was used to create horizontal indents or spaces, allowing typists to align text in a structured manner.
In the context of digital interfaces, "tab" refers to the ability to navigate through different elements or fields using the tab key on a keyboard. This concept dates back to early computer systems where tab navigation was integrated to move the focus between interactive elements, such as form fields or buttons, in a predetermined sequence.
Similarly, "order" in this context simply refers to the sequence or arrangement of elements that can be tabbed through. It ensures a logical flow of navigation within a user interface, making it easier for users to interact with the system.
