How to change text case.

Is ther a ‘change text case’ function I can use to change the text case when I’ve mistakenly typed it in the wrong case. If not, is there an addon . Thunderbird has this function which was very useful. I’m using EMClient as a front end for a Gmail account.

I very much would like this feature too. On Mac’s in a production environment, it is easy to hit a caps lock and type two sentences WITHOUT REALIZING YOU ARE TYPING ALL UPPERCASE.

In Outlook or Apple Mail, I can select any text and Choose make “lower case”; “UPPER CASE” or “Capitalize”

It is a great feature to reduce correction time and standardize email content.
