ReSharper Quick Reference
Version 1.0

Function	Shortcut (Default)	Description
Highlight symbol usage	Ctrl + Shift + F7	Highlights highlight usages of any symbol in your code. Position the caret at the symbol you want to search for in the editor, and press Ctrl + Shift + F7. Read accesses and the write accesses are highlighted in different colors.
Comment selection - Line	Ctrl + /	Comments or uncomments the currently selected block using line comments (// example). Comparable to default VS chord command
Comment selection - Block	Ctrl + Shift + /	Comments or uncomments the currently selected block using line comments (/* example */).
Expand current selection	Ctrl + W	Extends current selection, successively selecting word, line, inner block, block, method, etc. (depending on code structure).
Contract current selection	Ctrl + Shift + W	Contracts current selection, reverse of expand current selection. Does not appear to fully work/cycle down, stops after a few attempts.
Stack trace explorer	Ctrl + Shift + E	You need to copy the contents of a stack trace on the clipboard first. After doing so, open the stack trace explorer and you can navigate to the lines of code listed as part of the stack trace.
Duplicate selection	Ctrl + D	Duplicate currently selected line or block of code, inserts below current selection.
Format code - current file	Ctrl + Alt + F	Invokes ReSharper's code formatting engine on the current file.
Remove unnecessary using directives	Ctrl + Alt + O	Removes any unused or redundant using directives from your code. Shortens redundantly qualified references where possible. Example: using System + System.String, System.String can be unqualified to String.
Show method signatures	Ctrl + P	Within a method call's parameter list, press Ctrl + P and a list of possible signatures with summary (from xml comments).
Insert code	Alt + Insert	Triggers code generation, displays pop-up menu that lets you choose to insert constructors, property accessors, implemented interface members and overridden inherited methods. Works smartly, e.g., will generate property accessors for multiple values, but only lists member fields without existing accessors, will let you quickly pick member fields to initialize in an overloaded constructor. Worth experimenting with.
Surround with	Ctrl + Alt + J	Does just about what it sounds like--allows you to surround the currently selected block of code with various code constructs. Examples: #region #endregion, do… while, lock, using. These surrounding snippets are customizable.
Insert template	Ctrl + J	Opens a pop-up menu for inserting a code template at the current selection. ReSharper's Live Templates can also be invoked by typing the abbreviation for the template and then pressing the Tab key. Example: "itar" and then Tab = basic for loop where you can tab through and change the counter, bound, iterated object, source, etc. These are fully customizable.
Type completion	Ctrl + Alt + Space	Type a letter or two for the type you're thinking of. Hit Ctrl + Alt + Space, ReSharper will display a list of possible suggestions that you can select to complete the type name. Additionally, if you lack the attendant using declaration in your code after selecting a given type, ReSharper adds it. Example: in a file without a using declaration to System.Xml, in class or method type "xm" and Ctrl + Alt + Space. Type "ln", select XmlNodeChangedEventArgs. The type name is completed and System.Xml is added to your using declarations.
Smart completion	Ctrl + Shift + Space	Selects from a list of types, methods and variables to try and match the expected type of an expression. Example: create a method that returns int. Within its body, type "return ", press Ctrl + Alt + Space, a popup list of available variables of int type will appear.

Navigate previous error/warning	Shift + F2	Cycles cursor to the previous error or warning in your code.
