To do subscript in Google Docs, follow these steps:

1. Open your Google Docs document.
2. Highlight the text or character you want to make subscript. If you want to type new subscript text, place the cursor where you want it.
3. Click on the Format menu in the top toolbar.
4. Hover over Text , then select Subscript from the submenu.

The selected text will become smaller and positioned slightly below the baseline, appearing as subscript

. Alternatively, you can use keyboard shortcuts:

• On Windows or Chromebook: press Ctrl + , (Control key and comma)
• On Mac: press ⌘ + , (Command key and comma)

This shortcut toggles subscript formatting on the selected text or at the cursor position

. If using the Google Docs mobile app:

• Highlight the text.
• Tap the "A" icon (text formatting).
• Choose the subscript option (usually shown as "X₂")

This method is commonly used for chemical formulas, mathematical expressions, or any text that needs to appear below the normal text line
