Frequently Asked Questions About Slice Text
How do negative indices work?
Negative indices count from the end of the text. For example, -1 is the last character, -2 is the second-to-last, etc. This matches JavaScript/Python array slicing behavior.
What happens if my end index exceeds the text length?
The tool automatically clamps to the text boundaries, so you will get the text from the start position to the end.
