Browse Project Symbols command
The Browse Project Symbols command opens a dialog box containing a list of all symbols in the project. You can select a symbol from the list, or you can type in a symbol name. When the dialog box first appears, the word under the cursor is automatically loaded into the Symbol text box.
When you start typing into the Browse… dialog boxes, the list is automatically filtered down to match what you’ve typed. This makes it easy to get to a given symbol, usually by typing only a few characters.
