Once upon a time, you could strip formatting from the clipboard in notepad with ^V ^A ^C, for example if you were trying to paste from edge into word. There's still a market for a non-rich text editor, without autosave, cloud, account login or AI.
Unless it changed recently, the faster way is to just press ctrl+shift+V for "paste special" in Word, which should open up the paste dialog with "Unformated Text" preselected (IIRC), so immediately pressing Enter should close the dialog and paste the stripped text.
Apparently pasting unformatted text in browsers can be done with Ctrl+Shift+V. Pasting it in Office is Ctrl+Alt+V. Always the odd one out. Taken from here: https://devblogs.microsoft.com/oldnewthing/20220906-00/?p=10...
