+**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/ra_ide/src/hover.rs#L63[hover.rs]
+
+Shows additional information, like type of an expression or documentation for definition when "focusing" code.
+Focusing is usually hovering with a mouse, but can also be triggered with a shortcut.
+
+
+=== Inlay Hints
+**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/ra_ide/src/inlay_hints.rs#L40[inlay_hints.rs]
+
+rust-analyzer shows additional information inline with the source code.
+Editors usually render this using read-only virtual text snippets interspersed with code.
+
+rust-analyzer shows hits for
+
+* types of local variables
+* names of function arguments
+* types of chained expressions
+
+**Note:** VS Code does not have native support for inlay hints https://github.com/microsoft/vscode/issues/16221[yet] and the hints are implemented using decorations.
+This approach has limitations, the caret movement and bracket highlighting near the edges of the hint may be weird:
+https://github.com/rust-analyzer/rust-analyzer/issues/1623[1], https://github.com/rust-analyzer/rust-analyzer/issues/3453[2].

+=== Magic Completions
+**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/ra_ide/src/completion.rs#L38[completion.rs]
+
+In addition to usual reference completion, rust-analyzer provides some ✨magic✨
+completions as well:
+
+Keywords like `if`, `else` `while`, `loop` are completed with braces, and cursor
+is placed at the appropriate position. Even though `if` is easy to type, you
+still want to complete it, to get ` { }` for free! `return` is inserted with a
+space or `;` depending on the return type of the function.
+
+When completing a function call, `()` are automatically inserted. If a function
+takes arguments, the cursor is positioned inside the parenthesis.
+
+There are postfix completions, which can be triggered by typing something like
+`foo().if`. The word after `.` determines postfix completion. Possible variants are:
+
+- `expr.if` -> `if expr {}` or `if let ... {}` for `Option` or `Result`
+- `expr.match` -> `match expr {}`
+- `expr.while` -> `while expr {}` or `while let ... {}` for `Option` or `Result`
+- `expr.ref` -> `&expr`
+- `expr.refm` -> `&mut expr`
+- `expr.not` -> `!expr`
+- `expr.dbg` -> `dbg!(expr)`
+
+There also snippet completions:
+
+.Expressions
+- `pd` -> `println!("{:?}")`
+- `ppd` -> `println!("{:#?}")`
+
+.Items
+- `tfn` -> `#[test] fn f(){}`
+- `tmod` ->
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+
+    #[test]
+    fn test_fn() {}
+}
+```
+
+
+=== Matching Brace
+**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/ra_ide/src/matching_brace.rs#L3[matching_brace.rs]
+
+If the cursor is on any brace (`<>(){}[]`) which is a part of a brace-pair,
+moves cursor to the matching brace. It uses the actual parser to determine
+braces, so it won't confuse generics with comparisons.

+=== On Typing Assists
+**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/ra_ide/src/typing.rs#L35[typing.rs]
+
+Some features trigger on typing certain characters:
+
+- typing `let =` tries to smartly add `;` if `=` is followed by an existing expression
+- Enter inside comments automatically inserts `///`
+- typing `.` in a chain method call auto-indents
+
+
+=== Parent Module
+**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/ra_ide/src/parent_module.rs#L12[parent_module.rs]
+
+Navigates to the parent module of the current module.

+Shows a popup suggesting to run a test/benchmark/binary **at the current cursor
+location**. Super useful for repeatedly running just a single test. Do bind this
+to a shortcut!

+=== Semantic Syntax Highlighting
+**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/ra_ide/src/syntax_highlighting.rs#L33[syntax_highlighting.rs]
+
+rust-analyzer highlights the code semantically.
+For example, `bar` in `foo::Bar` might be colored differently depending on whether `Bar` is an enum or a trait.
+rust-analyzer does not specify colors directly, instead it assigns tag (like `struct`) and a set of modifiers (like `declaration`) to each token.
+It's up to the client to map those to specific colors.
+
+The general rule is that a reference to an entity gets colored the same way as the entity itself.
+We also give special modifier for `mut` and `&mut` local variables.
+
+
+=== Show Syntax Tree
+**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/ra_ide/src/syntax_tree.rs#L9[syntax_tree.rs]

+rust-analyzer itself.

+=== Structural Seach and Replace
+**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/ra_ide/src/ssr.rs#L26[ssr.rs]
+
+Search and replace with named wildcards that will match any expression.
+The syntax for a structural search replace command is `<search_pattern> ==>> <replace_pattern>`.
+A `$<name>:expr` placeholder in the search pattern will match any expression and `$<name>` will reference it in the replacement.
+Available via the command `rust-analyzer.ssr`.
+
+```rust
+// Using structural search replace command [foo($a:expr, $b:expr) ==>> ($a).foo($b)]
+
+// BEFORE
+String::from(foo(y + 5, z))
+
+// AFTER
+String::from((y + 5).foo(z))
+```

+=== Workspace Symbol
+**Source:** https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/ra_ide_db/src/symbol_index.rs#L113[symbol_index.rs]
+
+Uses fuzzy-search to find types, modules and functions by name across your
+project and dependencies. This is **the** most useful feature, which improves code
+navigation tremendously. It mostly works on top of the built-in LSP
+functionality, however `#` and `*` symbols can be used to narrow down the
+search. Specifically,
+
+- `Foo` searches for `Foo` type in the current workspace
+- `foo#` searches for `foo` function in the current workspace
+- `Foo*` searches for `Foo` type among dependencies, including `stdlib`
+- `foo#*` searches for `foo` function among dependencies
+
+That is, `#` switches from "types" to all symbols, `*` switches from the current
+workspace to dependencies.
