Hi Mat,

You can do it via the localization (https://world.optimizely.com/documentation/developer-guides/CMS/globalization/localizing-the-user-interface/). Just create a new XML with the following structure and replace the labels as required:

<?xml version="1.0" encoding="utf-8"?>
<languages>
    <language name="English" id="en">
        <episerver>
            <forms>
                <viewmode>
                    <stepnavigation>
                        <previous>Previous step</previous>
                        <next>Next step</next>
                    </stepnavigation>
                </viewmode>
            </forms>
        </episerver>
    </language>
</languages>

Hi again,

So, I think the documentation is pretty good on localization, but as a summary:

1. By default, UI localization is handled by XML files in Optimizely CMS.
2. The default path for these XMLs is a folder called "lang" under the content root.
3. You create XMLs with a specified structure allowing you to override existing strings.

An example is in Foundation: https://github.com/episerver/Foundation/tree/main/src/Foundation/lang

In short, you create the "lang" folder in your solution (if it doesn't exist already), create an XML (maybe call it Forms_EN.xml) and copy the snippet into it that I provided above. This will be (by default) picked up automatically from that location, if doesn't matter if content has already been created.

To find the XPath of an existing string so you can override it your best bet is to use a decompiler (like JustDecompile) and dig around in the assembly. Here is an old blog post (from CMS 7) that gives an idea of the structure and approach, whilst this is old the technique still holds up: https://getadigital.com/no/blogg/translating-episerver-ui/

Finally, it's actually possible to change the localization provider, if you want to make this stuff more accessible to editors I recommend the DbLocalizationProvider which is available as a NuGet package (https://github.com/valdisiljuconoks/localization-provider-epi).

Hope that's enough detail to get you started.
