Help with Replace

[Otto Scho]

Dear Community,
I need to Do the following in Notepad:

I want to use the Replace to delete everything after FOG
FROM: (ARGF41FOG06271)
TO: ( ARGF41)
how can I do such things?
It is just like in Excel: Replace FOG* with empty.
Thank you in Advance

In the search dialogue, check the regular expression checkbox and use the following search term FOG.+?\b to replace it with an empty string.
