Is there "Search and Replace in All Project Sources" function in STM32CubeIDE editor?
I need to change all occurences of variable names. These names happen to be in a lot of .C and .H files hundred times. Source is from a collegue with "xz2b3" kinda variable names. I'd like to change variables to longer, more talkative names. Some IDE editors feature some Ctrl-Shift-F for this purpose. Any tip?
