1. **Correct Use of the Enter Key in Entering Text:** - The Enter key is primarily used to create a new paragraph or line in text documents. When you press Enter, it signals the end of the current paragraph and starts a new one. In some applications, pressing Enter may also execute a command or submit a form, so it's important to be aware of the context in which you are working. For instance, in chat applications, pressing Enter sends the message, while in word processors, it creates a new line. 2. **Suitable Font Sizes for Ordinary Text in Documents:** - Generally, a font size of 10 to 12 points is suitable for ordinary text in documents. This range ensures readability while maintaining a professional appearance. For headings, larger sizes (e.g., 14 to 18 points) can be used to create a clear hierarchy in the document. 3. **Aspects to Keep in Mind When Choosing a Font for a Document:** - **Readability:** The font should be easy to read, especially in longer texts. Sans-serif fonts like Arial or Helvetica are often preferred for digital documents, while serif fonts like Times New Roman are commonly used in printed materials. - **Tone and Purpose:** The font should match the tone of the document. For example, a formal report may require a more traditional font, while a creative project might benefit from a more modern or artistic font. 4. **Purpose of the Following Keyboard Shortcuts:** - a) **:** This shortcut is used to save the current document or file. It is a quick way to ensure that your work is saved without navigating through menus. - b) **:** This shortcut is used to bold the selected text. It allows users to emphasize certain words or phrases quickly, enhancing the visual impact of the text.
