Is it possible to automatically change pasted text to all lowercase ?

Hi

Yes - you just use the lower(string) function - for example:

'Text (multiline)' := lower('Email Body')

which assigns a lower case version of the 'Email Body' field to the 'Text (multiline)' field

You should bookmark the language reference in the manual:

I have it open most of the time!
