+## Search rustc docs

+You can prefix a **//** (double slash) before the keyword to search all of

+> It doesn't make sense to have a built-in search-index of **rustc** since the **rustc** is changed 
+> very frequently. Therefore, you need to open the **rustc** docs page in advance to sync the 
+> search-index before you search **rustc** docs. However, the search-index of **rustc** is big, 
+> we never persist it to the local storage (due to the limited storage size available 
+> to browser extension).
 
 ## Search with type mode
 
 You can prefix a type to get the exclusive search result. Those type keywords including:
-- mod
-- struct
-- enum
-- fn
-- trait
-- type
-- macro
-- const
+- **mod**
+- **struct**
+- **enum**
+- **fn**
+- **trait**
+- **type**
+- **macro**
+- **const**
 
 For example, `fn:asref` to search function or `trait:iterator` to search trait.

-## Offline mode, search local Rust docs
+## Source code mode
+
+Since **v1.2**, we can straight open the source code page for our docs search result.
+Simply prefix `src:` (or `s:`, an alias to `src:`) before the keyword, you'll be 
+redirected to the correct source code line of your search result after you press `Enter`.
+For example, input `src:try_fold` or `s:try_fold`, you'll open the source code line of `std::iter::Iterator::try_fold()`.

+## Offline mode: search local Rust docs
 
 You can run command `rustup doc --std` to open the offline std docs. 
 To enable the offline mode, you should check the checkbox and input the offline docs path on the popup page.
