Search Everywhere is super useful in PyCharm. Use “Shift Shift” shortcut for easy access.

When working with a lot of files having the ability to search through everything is very useful.
Pycharm has a very nice “Search Everywhere” option accessible either by clicking on the magnifying glass icon or using double Shift shortcut.
