Simple functionality that lets you search words in the edited code.

[B-CE]

Sorry @krzys-h , #884 is a bit different, asking it for satCom / helping side.
(more like the current title there in fact ^^)

Btw, the @tomangelo2 ' description seam more asking for a search function into code editor,
and I was looking for such also 👍

(the title may have to be change to : "Searching in the code editor" )
