The Tools→Translation menu allows you to override default (system) text for site elements for any enabled locale.
To update a translation or label, click the text you would like to change, and then enter the new text in the text box that appears. After you've changed the text, it appears in the translation grid. Default text appears in italics, but new labels appear as regular text.
You can filter the list using the Group or Resource Key columns. The value in the Group column corresponds to the site element where the text appears.
You can import and export your custom translations from this page. This action is performed separately from the site import and export.
The word "remote" in a job search needs to be entered in the keyword box, not under Search by Location. In this example, Best Run wants to relabel the keyword search box to Search by Keyword / Remote positions.

This is how this system text was modified from Tools→Translations.
