Is there a way to have code templates for "if", "for" (or) for any multiline commands in terminal?

Question

Code templates are handy and help in finishing codes without error.

I am aware that notepad editors like atom provide code templates for if and for loop for bash.

Also aware that man pages provide assistance in understanding the syntax. For e.g., man $SHELL helps to understand the if and for commands.

But, I was wondering if there is a way to bring code templates into a terminal itself rather than using a code editor? This will help us to be more productive.

Let me give a use case scenario.

For this post to be solved, I wanted to have a for loop and then a if loop encased in that.

So if a template for for loop can be generated by some shortcuts in the terminal such that

for i in **type words here**; do 

    **type words here** 

done

Then I go inside the for loop template and then click another shortcut for the ```if````

for i in **type words here**; do 

    if [ **type words here**]; then
       **type words here**     
    fi

done
