 1. **Launch Claude**: Run `:ClaudeCode` to open Claude in a split terminal
-2. **Send context**:
-   - Select text in visual mode and use `<leader>av` to send it to Claude
-   - In `nvim-tree` or `neo-tree`, press `<leader>as` on a file to add it to the context
+2. **Send context**: Select text and run `:'<,'>ClaudeCodeSend` to send it to Claude
