Claude Code v2.1.90 adds mouse support with CLAUDE_CODE_NO_FLICKER flag
Claude Code update adds mouse interaction capability
Anthropic has released version 2.1.90 of Claude Code with a new feature that enables mouse support within the chat interface. This addresses a common workflow issue where users previously had to use backspace navigation to correct errors.
How to enable the feature
To activate mouse support, users need to:
- Update to Claude Code version 2.1.90
- Run the command with the environment variable set:
CLAUDE_CODE_NO_FLICKER=1 claude
The environment variable name suggests this feature may be addressing display flickering issues that previously prevented mouse interaction. Environment variables like this are commonly used in command-line tools to enable experimental features or toggle specific behaviors without requiring configuration file changes.
For developers using AI coding agents, mouse support in terminal-based tools can significantly improve editing workflows by allowing direct cursor placement and text selection, reducing reliance on keyboard-only navigation. This type of incremental improvement is typical in developer tooling where small quality-of-life features can have substantial impact on daily usage patterns.
