In STEM 7.4, a comprehensive Find function was added to the Editor to make it possible to search for elements, text and values in views, elements, formulae and notes. For example, you can search for elements by name, for numbers or user labels in formulae, and for particular content in text boxes.
In STEM 7.5, the complementary Replace function has been added, which will enable you to modify all of the things you could previously just find! The most common use of this functionality is likely to be modification of element names.
