project “search” needed- e.g. in equivalent of “Edit” menu

[dr-matt-smith]

I want to search for “source” in the celbridge-docs project, since I’m getting a make error

but I can’t find any search all files option

please can
(a)
an all files search be implemented

(b)
something like the Edit or Search menu
(I just tried out Spyder and there is a Search menu with a “Search text in files…” dialog …)
