Figure 7.6: The result of applying tab triggers to an HTML page.

Similarly, when writing Ruby code, typing def ⇥ in Atom creates a Ruby define statement to make a function, which looks like this:

def method_name end

After typing the name of the function (which replaces the placeholder text method_name), we can hit again ⇥ to place the cursor in the right location to start writing the main part of the function. These sorts of auto-expansions of content can speed up code production considerably, while also lowering the cognitive load of programming. We’ll see a concrete example of this technique in Section 7.2.

Finally, it’s possible to define tab triggers of your own. My own editing makes extensive use of tab triggers; for example, to make the text in Listing 7.1, instead of typing

Box~
ef{aside:technical_sophistication_text_editor}

by hand I used the custom tab trigger bref (for “box reference”) to generate

Box~
ef{aside:}

and then filled in the label technical_sophistication using autocomplete (Section 7.1.1). Defining custom tab triggers is highly editor-dependent and is beyond the scope of this tutorial, but some hints about how to figure it out for yourself appear in Section 7.5.
