Control+W / Control+Shift+W
The Extend Selection command allows you to successively select expanding logical blocks of code so that you can easily select any expression in the code by placing the caret somewhere inside it and pressing Control+W a few times. The command is also available in the main menu: .
Shrink Selection does exactly the opposite. Press Control+Shift+W or choose in the main menu to apply this command.
With CamelHumps (the Use CamelHumps for navigation checkbox on the page of dotPeek options), the Extend/Shrink selection commands work in a slightly different way.
If the CamelHumps is enabled, the Extend/Shrink Selection commands take into account parts of compound names. Suppose you have placed the caret in the middle of a compound name with several parts that begin with uppercase letters: With CamelHumps, pressing Control+W for the first time selects the current part of the word: Only after pressing this keystroke for the second time dotPeek selects the whole word: All subsequent presses are processed as usual.
This feature is inspired by and borrowed from JetBrains ReSharper, a developer productivity tool for Microsoft Visual Studio.
