If you have ever given your PC keyboard a good look, you have probably noticed the Insert key—it is typically located in the top key section right above the arrow key cluster. If you have never used it, you might be wondering, “Why do I need the Insert key?” If you are not sure what exactly the Insert key is for, you’ve come to the right place. In this post, we will tell you exactly what it is for and give you the steps for how to disable it. Let’s get started.

What Is the Insert Key Used For?

The Insert key is mainly used for switching between the two modes of entering text: overtype mode and insert mode.

  • In overtype mode, the characters you are typing overwrite the existing charters. So, basically, you will be typing over the text that you have already entered.
  • In insert mode, on the contrary, you type the characters in their current positions, with all the characters that already exist on your page being shifted to the right.

It is useful to note that the insert/overtype mode switching is not meant for overall operations on your PC or even a particular application. Switching the modes by pressing the Insert key is valid only for the window you are working with at the moment. In many modern applications, insert mode is set by default, but the user can switch to overtype mode by pressing the Insert key.

You can use the Insert key function in a variety of situations. That said, if you don’t need it, having the Insert key enabled on your PC can get irritating.

For instance, if you press the Insert key by mistake, the overtype mode will be activated automatically and the text you are currently typing will be overwritten. If you are working on something very important, it may start causing serious problems. So, you might reasonably ask: “How to turn off the Insert key in Windows 10?”
