Google owes its status as the most widely used search engine on the Internet to its efficient blend of simplicity, ease of use, and quality-of-life features, contrasting with models exemplified by search engines like Yahoo wherein a lot of content is already displayed up front. Even search engines that present themselves as alternatives to the digital giant, however, use an auto-suggestion function to guide users toward what they might have in mind while they are typing out their intended query.
On Google itself, the function is called "Autocomplete" and is present within both the search bar on Google's landing page and the browser extension that is commonly used to place a smaller version of that bar within the user's browser interface. When the text cursor is active inside the bar, the act of typing out several letters will prompt the service to produce a drop-down menu showcasing text strings that start with those letters and complete them logically.
The terms generated are always the most commonly queried ones in general, and there is always the option to directly click on one of the terms to instantly conduct a Google search for that precise string. This might save time for some users, but the more relevant benefit by far for having the search function predict the user's query is that it allows users to hone in on a likely term they may not be confident about the spelling of.
Perhaps unexpectedly, Google Autocomplete can also be useful for web marketers and SEO workers because of how it can show how many variations on a potential keyword are already in popular use by potential competitors. If there is a need to document lists of these predicted terms, however, there is no obvious method of copying them onto the computer's clipboard. It becomes possible through an ironic twisting of Google's own service functions, however; clicking the "Report inappropriate predictions" link will spawn a checklist consisting of those terms. Without actually using the report function, the text cursor can be dragged across the text itself so that it can be copied all at once.
