I only know how to do this on Windows (but it should look like any OS, you just need to find the right location yourself - a Google search will help with this).
On Windows:
Go to your User Folder - in Windows 7/8 it will be:
[SYSDRIVE]:\Users\[your username] (for example, C:\Users\JohnDoe\ )
This folder should have a folder named .AndroidStudioBeta or .AndroidStudio (pay attention to the period at the beginning - so it will be hidden on some operating systems).
Delete this folder (or, even better, move it to the backup location to return it if something goes wrong).
This should match reset to your Android Studio settings.
