The centerline symbol is not a standard symbol in Microsoft Word, but you can easily add it to your document using the following steps:

1. Click on the "Insert" tab in the ribbon at the top of the screen.
2. Click on the "Symbol" button in the "Symbols" group.
3. Select "More Symbols" at the bottom of the drop-down menu.
4. In the "Symbol" dialog box, select "Arial Unicode MS" from the "Font" drop-down menu.
5. Scroll down the list of symbols until you find the centerline symbol (it looks like a vertical line with a horizontal line through the middle).
6. Click on the centerline symbol to select it, and then click on the "Insert" button.
7. The centerline symbol will now be inserted into your document at the current cursor position.

Alternatively, you can also use the keyboard shortcut "Alt+8214" to insert the centerline symbol. Simply hold down the "Alt" key and type "8214" on the numeric keypad, then release the "Alt" key. The centerline symbol will be inserted at the current cursor position.
