Sally will clear and set tabs in the Tabs dialog box. Desi will set and clear tabs on the Horizontal Ruler.

Who is correctly setting and clearing tabs?

Both are correct.

This is what appears when I type "set tabs" in the Help search box in Word:

Do any of the following:

Set a tab stop using the ruler

Set a tab stop by using the dialog box

Remove a tab stop


Each of those choices is a link, and you can find more information online. Here's the Help section for Word for Mac 2011: http://office.microsoft.com/en-us/mac-word-help/learning-roadmap-for-word-for-mac-2011-HA103528093.aspx
Scroll down to read #6. In these directions, the ruler is called "the ribbon" but the results are the same.

Based on the information provided, both Sally and Desi are correctly setting and clearing tabs, but they are using different methods. Sally is using the Tabs dialog box, while Desi is using the Horizontal Ruler.

To set and clear tabs in the Tabs dialog box:

1. Open the document in the software application you are using, such as Microsoft Word.
2. Go to the "Page Layout" or "Layout" tab (location may vary depending on the software)
3. Look for the "Paragraph" or "Paragraph Layout" group and click on the small arrow or icon in the bottom right corner of the group. This will open the Paragraph dialog box.
4. In the Paragraph dialog box, click on the "Tabs" button. This will open the Tabs dialog box.
5. In the Tabs dialog box, you can set and clear tabs on the ruler. You can set tabs by entering the desired position in the "Tab stop position" field and selecting the desired alignment (e.g., left, center, right, etc.). To set a tab, click the "Set" button. To clear a tab, select the tab you want to remove and click the "Clear" button. Repeat this process for each tab you want to set or clear.
6. Once you have set or cleared all the desired tabs, click the "OK" button to close the Tabs dialog box.
7. Click the "OK" button again to close the Paragraph dialog box.

To set and clear tabs on the Horizontal Ruler:

1. Open the document in the software application you are using, such as Microsoft Word.
2. If the Horizontal Ruler is not visible, go to the "View" tab and make sure the "Ruler" option is selected.
3. On the Horizontal Ruler, you will see several small rectangular markers. These markers represent the default tab positions. If you want to change the tab positions, click and drag the markers to the desired positions. To set a new tab, simply click on the ruler at the desired position. To clear a tab, click and drag it off the ruler or simply right-click on the tab and select "Clear".
4. Repeat the process to set or clear all the desired tabs.
5. Save your document.

Both methods allow for the setting and clearing of tabs, but the choice of method may depend on personal preference or the specific software being used.
