Under the hood
Claude Code's terminal display now tracks mouse pointer presses, drags, releases and hovers with a capture model
What
The engine that draws Claude Code's terminal interface now explicitly handles mouse pointer presses, drags, releases and hovering, and can "capture" the pointer to a specific on-screen element for the duration of a drag. While an element holds the pointer captured, mouse wheel scrolling is suppressed.
Why
This is groundwork for more precise mouse interaction in the terminal UI, such as dragging something without the screen also scrolling underneath it at the same time.
