How to search file location for a particular function

[David_]

In STM32Cube, how do you word search for a particular function among dozens of HAL, middleware source files?  How to find MX_APPE_Process(); as appear in main() in main.c  TIA

[Tesla DeLorean]

Any kind of find-in-files or right click context option?

Outside, perhaps grep or a decent file manager?

[Karl Yamashita]

Place cursor on the function of interest and press F3 on keyboard which should select/open the file and jump to the function within it.

Also available on the right-click pop-up menu:

And, of course, there is the 'Search' menu:
