/tui Command — Switch Terminal Renderers / Claude Code v2.1.110

What

New slash command to switch between the classic main-screen renderer and the flicker-free fullscreen alt-screen renderer at runtime, without restarting.

Usage

/tui fullscreen    # Switch to flicker-free alt-screen rendering (mouse support included)
/tui default       # Switch back to the classic renderer

Details

The fullscreen renderer is equivalent to setting CLAUDE_CODE_NO_FLICKER=1 but can now be toggled within a session
A new tui setting is persisted in global config, accepting "default" or "fullscreen"
When switching to fullscreen, you'll see hints about mouse support: click to move your cursor, click to expand collapsed tool results, and text auto-copies on selection
A new tip ("Try flicker-free rendering, now with mouse support · /tui fullscreen") will appear for users on the classic renderer

Evidence

/tui command handler (search for "Usage: /tui <" and "Set the terminal UI renderer")

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