Modify the label that appears above a Relate field's search box

This is rendered using label - LBL_SEARCH_SELECT_MODULE, and is formatted as "Select {{module}}" by default. You can update this label just for your module in custom folder for your requirement :) 

Would you mind telling me the full deployment path for the label file? It's tricky finding it since I'm cloud only

LBL_SEARCH_SELECT_MODULE is defined in the app_strings (include/language/en_us.lang.php) but you can define in the mod_strings so the changes will affect a specific module instead of whole relate fields.

So it's custom/Extension/modules/[module]/Ext/Language/en_UK.[name].php

and it should contain

<?php

$mod_strings['LBL_SEARCH_SELECT_MODULE '] = '[custom label]';

is that right?

Yes!

Thank you for your help!

Hi André, I've tried to deploy this but it hasn't worked- are you able to advise?

From the manifest file:

4=>
array(
'from' => '<basepath>/files/en_UK.SearchSelect.php',
'to' => 'custom/Extension/modules/Accounts/Ext/Language/en_UK.SearchSelect.php'
),

From the file en_UK.SearchSelect.php:

<?php

$mod_strings['LBL_SEARCH_SELECT_MODULE '] = 'Select Record';

The Relate field appears in the Correspondence module, and relates to the Accounts module

Did you try on a local instance prior to ondemand?

No we're ondemand only
