Using Document Symbols
Open a BASIC program file to view all the symbols in the current document in VS Code outline window.
If you click a symbol in the outline window, the cursor will indicate its location.
You can also use a command to find a symbol. Press Ctrl + P to open the search window and then enter @ to list all symbols in current document.
Type the first few characters of a symbol in the command window to filter the results, and then click the corresponding symbol to jump to its definition location.
