Most IDEs will have a button/icon for the compile of the current selected/active source file; a build button; and a run/execute button.
There will be buttons for standard file manipulation of the current file (like most Windows programs have) and then buttons specifically related to either programming and/or the compiler actions.
Best bet would be to look at the tool tips assigned to each button and figure out the association to the current file/project. Then do the same for the menu options.
This method spends a lot of time and seems redundant/wasteful, but without a user manual and/or a human guide, it will at least allow you to get a glimmer of what is available from that IDE.
Good luck.
