Find and replace text on intellij idea by using (ctrl+R) or (ctrl+shift+R) for windows.
Find and replace
If you want to find and replace word on a file just use (Ctrl+R).
But if you need to replace word in all file, you can use (Ctrl+Shift+R) shortcut.
For example search and replace in all file, see image below:
In the search panel, you can determine the searching location. If you see image above, you can find four option tabs (In project, Module, Directory or Scope).
The crazy things about search in intellij idea is “fast!” and really-really fast. I do not find this kind of experience in any other IDE. You can also using regex or matching file with extention too if really needed.
