I am trying to find the variable name for the content link in a view.

{{ kint(content) }} makes the page crash, probably because the variable is too big.

The same is true for the following code.

function my_theme_preprocess_field(&$variables, $hook) {

How can I find out what I am looking for?

Usually D8 $variables contain way too much data, and browser struggle to render it for you. I strongly suggest to use xdebug or similar debugger, all modern IDEs support it. It makes developer's life much easier. However, there is a workaround without having xdebug configured:

function my_theme_preprocess_field(&$variables, $hook) {
    // or better:
    // or:

This will return you top-level keys, then you can drill down to the next level:


For objects use type casting:

dpm((array) array_keys($object));

Set Kint as Variables Dumper on /admin/config/development/devel (with Devel Kint module enabled) and you'll get nicely structured output.

In Twig templates you can use something like this:

{% for key, value in content %}
    {{ key }}
{% endfor %}

UPD: Valuable comment from Kevin for TWIG:

{{ kint(content|keys) }}

    in twig template you can use {{ kint(content|keys }}
