Go to Derived Symbols
Ctrl+Alt+B
This command gets the list of all derived symbols for the current symbol and lets you navigate directly to one of them, down the inheritance hierarchy. There is a similar command, Go to Implementation, which lists only implementations, without intermediate steps in the inheritance chain.
You can invoke this command from the Solution Explorer, from the Structure window and other tool windows. If necessary, you can navigate in the opposite direction with the Go to Base Symbols command.
Navigate to derived symbols
Place the caret at a symbol in the editor or select the symbol in the Structure tool window.
Press Ctrl+Alt+B, choose in the main menu, or click the symbol holding Ctrl+Alt keys.
If the symbol has only one derived symbol, JetBrains Rider navigates to it directly.
If the symbol has several derived symbols, they will be listed in a drop-down. The list may contain items in both bold and regular font. Bold indicates that an item has direct inheritance, while the regular font is used for indirect inheritance.
You can do one of the following:
Click the desired item to open it in the editor.
Select the desired item by pressing Up and Down and then press Enter to open it in the editor.
Start typing to filter results. Note that you can use CamelHumps here.
To view and analyze the list of matched items in the Find window, click Open in Find Window
, press Shift+Enter or + on the numeric keypad.
When a type or a member has inheritors in the current solution, you can see it by the presence of a special icon (for example, 
) that appears to the left of the declaration. You can click the icon to expand the list of derived symbols and navigate.
