DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.69

Mouse-Based Text Selection and Copy

What

Native mouse text selection with drag-to-select and clipboard copy support in the terminal UI.

Details
  • Click and drag to select text in the terminal output
  • Selected text can be copied to the system clipboard via OSC 52 escape sequence
  • noSelect regions prevent selection of UI chrome (status bars, borders) while allowing content selection
  • Selection state tracks anchor/focus positions with full drag handling
  • from-left-edge option extends no-select regions from the left edge of the terminal
Evidence

Text selection system (search for "isDragging", "copySelection", "noSelect")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
