Auto-complete code text problem (newbie)

Hi to all. I'm just starting to learn programming, but I encountered a small problem.
So when I write a line of code, e.g.


<em> Founder and CTO of The app Brewery. </em>
And I'm trying to add <strong> atribute for example
<em> Founder and CTO of <strong> The app Brewery. </em>
Then after writing the <strong> code automatically adds </strong> so the result is this
<em> Founder and CTO of <strong> </strong> The app Brewery. </em>
While I would like to add the code myself that would look like this
<em> Founder and CTO of <strong> The app Brewery </strong> </em>
So is there a button at which the auto-complete option is turned off without disabling the auto-complete feature?
