Taking information from the internet or from other sources usually involves selecting the text, copying it into the clipboard, and then pasting it into your file. In today's modern applications pasting text will most of the time take its formating with it.
By formatting what I am talking about are parameters like font size, line breaks, hyperlinks, font styles, etc. and sometimes you do not want any of these in your file, you would like and prefer to have just plain text so you can format it as you wish.
In order to paste just plain text instead of using the CTRL + V keyboard shortcut, press CTRL + SHIFT + V instead. This shortcut will paste the only text into your file.
Leave it to Microsoft to make its shortcut not work in their application. In Microsoft Word, you can only use the standard CTRL + V shortcut, if you press CTRL + SHIFT + V nothing will happen. So in order to paste the only text into a word document, choose to paste special > text only
I have tried CTRL + SHIFT + V in various applications like photoshop, illustrator, InDesign, visual studio code, slack, discord, WordPress installations, etc and only one that has not worked for me was Word and office in general so you are safe to use this trick and have desired results.
