sorry the email client just cutted of the line here is the recipe for
better readablity
```
Start emacs with emacs -q
M-x fido-vertical-mode                    ;; fido-mode has the same
effect I tried
M-x rgrep
ethiopic                                           ;; the string to search
.                                                       ;; select
default=all for file type  by simply clicking just press Enter
~/Documents/src_codes/emacs      ;; select the directory to rgrep in
and press Enter
