I am writing a manual for an application. The manual describes how to operate a piece of software. Often I write sentences like:

> 
> Press "Compute" button, then change to "Statistics" tab.
> 
> 
> 

My colleague has added definite articles in front of each control's name. 

> 
> Press the "Compute" button, then change to the "Statistics" tab.
> 
> 
> 

I feel like it is wrong. Since neither of us is a native speaker, we are not sure whether to put or omit the definite article "the" in front of names of buttons. I could not find a rule on the web that applies to buttons and tabs. 

What is the correct way to formulate such a sentence: with or without the "the"?
