Something bothered me for a long time (unnoticed Capslock), then I decided to check for options in KM and after a short while I came up with this very short macro. It is based on the use/not use of caplock by 'author' giving either this: john doe... or JOHN DOE...
So I simply select the name/text and then run the macro. Sometimes it is all caps, because when I type I look at keys not on screen so I may chose 'Lowercase' instead of 'Title Case'
It's fun that KM even makes simple solutions happy moments
