Problem
The prompt editor currently relies on keyboard navigation for cursor placement and text editing. Editing longer multi-line prompts is slow, while enabling terminal mouse reporting can interfere with native terminal selection unless the feature is explicitly gated and restores terminal state reliably.
What changed
Add experimental mouse text selection to the main prompt editor, enabled with
KIMI_CODE_EXPERIMENTAL_TERMINAL_MOUSE_INPUT=1.The editor now supports click-to-position, forward and reverse drag selection, wrapped and multi-line ranges, grapheme-safe deletion and replacement, atomic undo, and selected-text retrieval.
Ctrl+Ccopies an active selection while preserving the existing cancel/exit behavior when no selection exists.Kimi Code handles SGR mouse input only while the main editor is mounted, coalesces high-frequency drag events, maps coordinates from the latest rendered layout and actual viewport, and disables mouse reporting around dialogs, external editing, reloads, normal exit, and emergency terminal restoration. Holding
Shiftkeeps terminal-native selection and scrollback behavior available.English and Chinese documentation, package changesets, and regression coverage are included.
