Segments containing a number, but not only a number?

The easiest solution is to use the display filer and enter \d

This forces Studio to show all segments with at least one digit. And at least one digit in a segment is a segment with a number.

Thank you, Jerzy! It worked like a charm. Where do I get those magic spells? :-) Is there a list?

I'm never satisfied: Is it possible to find all numbers with . or , in it? Like either 1.0 or 1,1? The source is in English but it contains both English decimal separator system and target system in source (so a lot of confusion, especially because some of it is machine translated). 

There is no list, you can learn regex from this website for example: https://www.regular-expressions.info/

In general:

\d is a digit

\w is a so called word character (includes letters and digits and other signs to build words)

\s is a space character

. matches any character

To find a dot you need to "escape" it, means \.

To find a date: \d\d\.\d\d\.\d\d\d\d => finds 15.01.2021 \d\d\\d\d-\d\d-\d\d finds 2021-01-15

and so on.

If you speak German, there are two webinars left on Regex: http://seminare.bdue.de/4888
The basics have already been covered, but are recorded, so I think you could get the recordings too.
