When you read only the parts of a written work that outline and summarize its content, you are skimming.

Skimming is a reading technique where you quickly scan a text to get the main idea and key points. It's useful for:

* Getting a general understanding of a topic.

* Deciding if a text is relevant to your needs.

* Reviewing material you've already read.

Here are some common skimming strategies:

* Read headings and subheadings.

* Look for boldface words and keywords.

* Read the first and last sentences of each paragraph.

* Scan for lists and bullet points.

Skimming is a valuable skill for efficient reading and can save you a lot of time.
