TYPESCROLLINSENSITIVE

TYPESCROLLINSENSITIVE is a term used in software development to describe a mode or flag that controls whether typing in a text display should affect the scroll position. The term is not part of a formal standard and is typically encountered in project-specific documentation or code comments as an identifier for a particular behavior.

In practice, TYPESCROLLINSENSITIVE denotes a boolean or bitmask value that, when enabled, prevents automatic scrolling in response to keyboard input or dynamic changes to the text content. This can help maintain a stable viewport during long edits or in interfaces with multiple panes, where automatic scrolling would be disruptive or confusing to the user.

This behavior is commonly employed in editors, chat or collaboration applications, and other text-heavy interfaces where the developer wants to decouple typing activity from viewport movement. When the flag is disabled or cleared, automatic scrolling may resume, ensuring that new content or edits remain visible as appropriate for the context.

Implementation considerations include how the flag is exposed in the API or configuration, and how it interacts with other scrolling controls or focus management. It is often represented as a simple boolean field or as part of a larger scrolling or view-behavior enumeration, and it may be paired with a corresponding TYPESCROLLSENSITIVE flag to re-enable automatic scrolling.

Accessibility and usability implications should be considered, as suppressing or triggering scrolling can affect how content updates are announced by assistive technologies and how users navigate with keyboard or other input methods. See also: scroll behavior, viewport management, text editors.
