Description:
The "Wizard" helps you create, understand, and debug Regular Expressions used by our Search and Replace for Windows grep utility. The wizard allows you to construct new expressions, or modify existing ones, using a term-by-term approach. The effect of specific operators is presented in-context, using colors to distinguish the active operator from other parts of the overall expression. A sample text you provide is used rather than an actual file.
