Lesson Content

The interface most users ignore.

Many new Claude users start a conversation, get a response, and never explore beyond the chat window. This is like sitting in a car and only knowing how to steer – there are controls, features, and settings that dramatically change the experience, and most of them are never discovered because they are not labeled with flashing signs.

This lesson gives you a complete orientation to the Claude interface.

Important note before we begin.

Claude's interface is actively developed. Features roll out gradually, differ by plan, and change with updates. Everything in this lesson reflects the Claude.ai interface as understood at the time of writing, but you should verify current availability and placement in your own interface. If something described here does not appear in your view, it may require a different plan tier or may have moved.

The main conversation interface.

When you open Claude.ai, the main area is the conversation window where you type and receive responses. Key elements:

• The message input box: Where you type. On most interfaces, pressing Enter sends the message. Shift+Enter creates a new line without sending. (Verify this in your interface – it may be configurable.)
• The attachment button (typically a paperclip or + icon): Lets you upload files, images, and documents for Claude to analyze.
• The conversation thread: Your full conversation history for the current session. You can scroll up to review earlier parts of the conversation.
• The new conversation button: Starts a fresh conversation. Each new conversation begins with no memory of previous ones (unless Projects is in use – covered in Lesson 3).

Conversation history.

Claude saves your past conversations (when you are logged in) so you can return to them later. Your conversation history is typically accessible in a sidebar or menu. You can:

• Search past conversations by keyword
• Continue a prior conversation by clicking on it
• Delete conversations you no longer need
• Rename conversations for easier organization (verify availability in your interface)

Sharing conversations.

Most interfaces allow you to share a conversation as a link. Shared conversations are read-only for the recipient – they can see the full exchange but not add to it. Before sharing any conversation, review it for sensitive information: client details, personal data, or anything you would not want publicly accessible if the link were forwarded.

The settings menu.

The settings area (typically accessible through a profile icon, account menu, or gear icon) contains important options including Custom Instructions – covered in detail in Lesson 2. Take a few minutes to explore your settings menu to understand what is configurable in your current interface version.

Model selection.

If you have access to multiple Claude models, you may be able to switch between them in the interface. Different models may vary in reasoning depth, speed, and context window. Verify current model options and their differences in your plan directly in the interface – capabilities change with model updates.

Keyboard shortcuts.

Many Claude interface versions support keyboard shortcuts for common actions. Check your interface's help menu or settings for available shortcuts – these save significant time for frequent users. Common shortcuts often include: submitting a message, starting a new conversation, and toggling the sidebar. Verify the current shortcut list in your interface rather than relying on any fixed list, as shortcuts change with interface updates.

Mobile vs. desktop interface.

Claude is available on desktop browsers and as a mobile app. The core conversation functionality is the same, but layout and feature availability may differ. Some features (like file uploads or Projects) may have limited support on mobile compared to desktop. Use the desktop interface for complex tasks involving file analysis, long documents, or multi-step projects.
