The TUI & Keybinds

OpenCode's terminal interface uses split panels for chat, file tree, and diff views. Tab switches between Plan and Build modes. This lesson covers the layout, navigation, and keyboard shortcuts.

What you'll learn

• Split-panel TUI: chat panel, file tree, diff viewer, all in one terminal window
• Tab key toggles between Plan mode (read-only) and Build mode (makes changes)
• /undo and /redo revert and restore changes

Build it

Launch the OpenCode interface and familiarize yourself with the core commands. Use these shortcuts to navigate modes, manage context, and control version history.

opencode
# Tab: toggle Plan/Build mode
# /init: analyze project and create AGENTS.md
# /undo: revert last change
# /redo: restore reverted change
# /share: create a shareable link to the conversation

What goes wrong

Mistake	How you notice it	The fix
Keybinds conflict with terminal	Tab or other keys don't work as expected	Customize keybinds in OpenCode config
Undo not available	/undo returns error	Undo only works for the most recent change in the current session
