On the Mac, if you don’t have a trackpad, you can hold down the shift key while scrolling your mouse. This enables you to scroll left & right. This is for all apps on the Mac, not just Airtable and not just Chrome.
Please try not to post in this thread if you have a technical question about how to do something in Airtable, because this thread is supposed to be for important feature requests that are missing from the product. Thank you!
