I mean this little bar in the text window on the right:
I cannot find it.
Format + Text + Show Ruler.
Merci beaucoup!
I think, that was too easy… currently I don‘t see the forest for the trees in TB
And there’s even a keyboard shortcut, which I think is built-in rather than one I’ve added:
Ctl-Cmd-R will toggle the ruler display on and off.
