IntelliJ beginning of file keyboard shortcut

Question

command+home or fn+command+left arrow

Edit the Intellij Preferences -> KeyMap -> Editor Actions entries for "Move Caret to Text Start" and "Move Caret to Text End". If you set those to Command+UpArrow and Command+DownArrow, it'll work like a normal text editor. I have no idea why that isn't the default in Intellij instead of the seemingly pointless "scroll one line" feature.

On Mac, command+home and command+end move to the top and bottom of the file.

On a Mac laptop, there are no home or end keys. Many key combinations with option/function keys produce missing keys and do other neat things. For instance, using function+left and function+right will provide windows-style home and end behaviour while function+up and function+down will provide page up and page down behaviour. Superuser has more information.

Also, if you open the Keyboard preferences pane and look at the Input Sources tab, you will find that the displayed keyboard changes as you press modifier keys such shift, option and function. Your keyboard probably does way more than you thought.

The accepted answer is not correct. To move to the beginning/end of a file, use ctrl+home/ctrl+end on Windows/Unix or command-home and command-end on the Mac, as @jackrabbit suggested.

ctrl+pageup (Move Caret to Page Top) moves the caret to the top of the viewable portion of the file (page, viewport). It also does not move the caret to the first column, it tries to stay in the same column that it was previously
