CodeRush provides the Selection Expand and Selection Reduce features. These features allow you to expand/reduce the selected text by logical code blocks.
Use the Selection Expand (Ctrl + W) command to select the code block when the caret is inside it. You can use the Selection Expand command multiple times to increase the selected box's size.
The Selection Reduce (Ctrl + Shift + W) does the opposite: it undoes Selection Expand and reduces the selected block.
You can also use NumPad Plus to expand and NumPad Minus to reduce the selection box's size.
Use one of the following ways to enable these shortcuts:
You can use the Selection Expand/Reduce feature in combination with the Include Previous/Next Element feature.
CodeRush shows a code preview in the code editor if a portion of the selected code falls outside the screen boundaries.
To enable this new code preview, go to the Editor | All Languages | Selection options page and enable the "Show code preview hints when selection changes" option.
