Advanced Features Explained
What is Case-Sensitive Search?
Case-sensitive search matches only the exact capitalization you enter. For example, "Apple" will not match "apple" or "APPLE" unless you uncheck the case-sensitive option.
What is a "Whole Word" Search?
Whole word search ensures that only complete words are matched. For example, searching for "cat" will not match the "cat" in "caterpillar" if this option is enabled.
Introduction to Regular Expressions (RegEx)
Regular Expressions (RegEx) are powerful patterns for advanced search and replace. Here are some useful examples:
- Remove all blank lines:
^\n - Find all email addresses:
[\w-\.]+@([\w-]+\.)+[\w-]4 - Add text to the beginning of every line:
^(Replace: Your Text)
