NightwatchJS Command to Repeat a Keystroke
Here’s a simple custom command that lets you repeat a specific key (single or combo) N number of times.
In the Drupal world you want to place this in your “Commands” directory (as defined in DRUPAL_NIGHTWATCH_SEARCH_DIRECTORY in web/core/.env).
You’d want to change “sitename” to be your site’s name (so it feels namespaced).
