Searching for files
To search for a particular file, press Control + P (or Command + P on a Mac) and type the search term. The source pane will display a list of all matching files as you type. You can use the up and down arrows to move through the list, and Return to open the file you want:
Searching within a file
To search for a particular substring in the file currently loaded into the source pane, press Control + F (or Command + F on a Mac) while the source pane is focused. Press Return to search. The debugger will display the number of matches in the code and highlight each result:
Using the Outline tab
You can further simplify the search by filtering the list. Enter text into the text input above the list to limit the results in the Outline. For example, if I enter "load" when viewing the above list, I get the following:
Only the functions with load in their name are shown.
This feature may not seem terribly useful when searching a file with a handful of functions in it but when you are searching through a file with dozens of functions, it comes in handy.
Searching in all files
You can also search for a string in all of the files included in the currently opened project. Press Shift + Ctrl + F (Windows and Linux) or Shift + Cmd + F (macOS) and then enter the string you are trying to find.
If the string exists in any of the files in the project, the search will return a list showing a list by file and line number.
Click on any entry in the list to go directly to the line in the file where the string occurs.
