None of these tips from TechRepublic Premium require a paid Google Workspace account, so anyone should be able to make use of them. You do, of course, need to have a Google account.

HOW TO PASTE WITHOUT FORMATTING

I use this tip all the time. When you copy and paste text into a Google Document, it almost always pastes the content along with formatting from the original source. Sometimes that’s okay, but most of the time, it’s not. For example, if I need to copy the output of a Linux command into a Google Doc, I want it unformatted. Or, maybe I copied a quote from an interview subject out of an email. Again, I don’t want the formatting.

To paste content without formatting, use the keyboard shortcut [Ctrl]+[- Shift]+[V] (or [Command]+[Shift]+[V] on macOS). This will paste whatever you’ve copied without any formatting.
