Can't copy-paste in Claude Code? "/tui default" and your back in business

If copy-paste stops working in Claude Code's terminal UI, running the command "/tui default" can restore the functionality and get the user back to work.

Background

- Claude Code is Anthropic's command-line coding agent; it lets developers run AI-powered coding tasks inside a terminal. - A recent update switched Claude Code to a TUI (Text User Interface) mode that captures mouse/keyboard input differently, breaking the standard copy-paste behavior many users expect in a terminal. - "/tui default" is a slash command that reverts Claude Code to its original terminal mode, restoring normal copy-paste functionality. - This is a quick workaround for developers who rely on terminal copy-paste (e.g. copying error messages or code snippets in/out of the AI session) and found the new interface disruptive.
