Press <kbd>Ctrl</kbd>+<kbd>T</kbd>, type something to find symbols, it triggers a drop-down list. Each entry on the list has two parts, left is a matched symbol, right is the file path. 2. If the symbol part on the left is short enough, there will be some room on the right to show the file path (usually just incomplete file path). We hover the mouse over the file path, it'll display a pop up to show the full file path as below  3. If the symbol's signature is **too long**, there won't be room on the right to show the file path at all. So cannot hover the mouse over the file path, thus no way to tell **which one is which** as seen below ![image](https://user-images.githubusercontent.com/19678455/146704159-8b01ae60-e1f3-4075-8ae6-078ad8f…
