What's the MacOS equivalent for Ctrl+Shift+V?

If you use the keyboard shortcut Control + Shift + V on Windows, it usually pastes the text from the clipboard without formatting.

Is there an equivalent shortcut for macOS?

Not all apps support this (MS Office, I'm looking at you) but many do including Apple's Apps.

Though is not without formatting Per Se. It is actually Paste and Match Style and you do it with:

ShiftCommandOptionv

From Apple Keyboard Shortcuts:

Option-Shift-Command-V: Paste and Match Style: Apply the style of the surrounding content to the item pasted within that content.

Please note that "The behavior of these shortcuts may vary with the app you're using."
