This sounds like a duplicate post but I tried to find answers to this question online and can't seem to find any helpful information...
I opened several downloaded class files that form one project, and can't seem to run the code. There is no toolbar with the run and debug button and the shortcut (^R) is not working. Right-clicking on the files neither gives the option to execute the code.

Looking at your screenshots (especially #2, the one that show the File menu) it seems to me that you are in the Light Edit mode where the whole IDE pretty much is just an editor.
Switch to the full IDE mode (where you open the actual project) and you will have the full functionality.
