paste
It is also called copy and paste. It is a way of highlighting text on the Internet and placing it in another place. Copy and paste does not remove the text from the original source. It is sometimes used to copy a large amount of text from the original source and put the text on another site, which is plagairism. It can also be used to copy a word or phrase from a search to paste it in a search box, to move text from one place in Word and move it to another place, etc.
Usually when you need to copy and paste, there is no need to use Paste Special. It is only used when you want to do something more unusual when you paste. If whatever you are copying is going to a new location in the same format as it was in its original place, which is normally the case, then the standard Paste is sufficient.
A normal copy and paste will do this. You can left click on the source cell and then right click and choose "copy". Then left click on the destination cell and right click and choose "paste". Alternatively, you can use Ctrl & c to copy and Ctrl & v to paste (which is a little quicker when you are used to it).
