Dear Ricardo, 

You can change the caption on the button in the Translation section (https://prnt.sc/odvfuk). You can find the record with the needed Key and change the caption in the English (United States) - Default column. For example, here are such records for New Contact button caption (https://prnt.sc/odvgsn). 

Best regards,

Dennis 

Thanks... It does work for existent sections, but it did not work for my new Students section. I changed the value of the new sections's "addNewRecordButtonCaption" from "New" to "New Student" in Translations, but button still shows "New"... 

Ricardo Bigio,

In this case you can do the following:

1) Open Section schema for your object (should be named like UsrTest1Section)

2) Find AddRecordButtonCaption and set Value to the needed caption, save the schema (https://prnt.sc/ofs9yy)

3) If you have only one edit page for the section, find the corresponding record in sysModuleEdit:

   3.1) select * from SysModule where Caption = '<Your section caption>'

   3.2) take SysModuleEntityId from there and paste into the query

          update sysModuleEdit set ActionKindCaption = 'Needed caption' where             SysModuleEntityId = 'SysModuleEntityId  you've found before'  

4) Clear cache and reenter the site. 

Best regards, 

Dennis 

Now it works... Thanks!
