Extend/shrink selection

Last modified: 15 May 2024

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 CtrlAlt0 a few times. The command is also available in the main menu: ReSharper | Edit | Extend Selection.

ReSharper: Extend selection ReSharper: Extend selection ReSharper: Extend selection ReSharper: Extend selection

Shrink Selection does exactly the opposite. Press CtrlAlt0 or choose ReSharper | Edit | Shrink Selection in the main menu to apply this command.

With CamelHumps (the Use CamelHumps checkbox on the Environment | Editor | Behavior page of ReSharper 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:

ReSharper: using CamelHumps to extend selection within a word

With CamelHumps, pressing CtrlAlt0 for the first time selects the current part of the word:

ReSharper: using CamelHumps to extend selection within a word

Only after pressing this keystroke for the second time ReSharper selects the whole word:

ReSharper: using CamelHumps to extend selection within a word

All subsequent presses are processed as usual.
