解説
問 58
Incorrectア
Indent is a formatting feature that inserts blank space at the beginning of a line in text or program code, making the hierarchy or structure easier to read. It is not a feature that presents input candidates to reduce keystrokes, so it is incorrect.
- イ
正解 The correct answer is イ, Autocomplete. Autocomplete is an input-assist feature that, triggered by the characters the user has begun to type (the first few characters), refers to past input history or a dictionary and displays a list of candidate strings that could follow. The user only has to pick one from the list instead of typing the rest, so it fully matches the question's requirement of reducing the effort of character input. Completion in a browser's address bar, a search box, or form fields are typical examples.
Incorrectウ
Auto filter is an extraction feature in spreadsheet software that narrows table data down to display only the rows matching a specific condition. It narrows the display of existing data rather than assisting character input, so it is incorrect.
Incorrectエ
A hyperlink is a referencing mechanism embedded in text or images within a document that, when clicked, moves to another page or location. It is meant for navigation and has nothing to do with presenting input candidates, so it is incorrect.
ここがポイント
- Autocomplete = an input-assist feature that, from the characters typed so far, refers to history and dictionaries and presents a list of candidate continuation strings to reduce the amount of typing.
- Distinguishing confusingly similar terms: Indent (indentation formatting), Auto filter (data extraction), and Hyperlink (reference jump) all differ in purpose from input completion.
