Which action would help a student quickly scan long articles found online?

To efficiently scan long articles found online, searching for keywords is the most effective action. By using a specific term or phrase related to the content they are interested in, students can quickly locate relevant sections of the article. This process typically involves using the browser's "Find" function, which highlights the occurrences of the keyword throughout the text. This targeted approach allows students to bypass unrelated information, thus saving time and increasing comprehension of key ideas within the article.

While scrolling using the mouse and pressing arrow keys may help navigate through the text, these methods do not provide a direct means to locate specific information. Tapping the space bar, on the other hand, usually causes the page to scroll down, but does not assist in locating important content. Therefore, searching for keywords stands out as the most effective strategy for quickly scanning articles and finding pertinent information.
