To increase indent of the current line:
Command + W, then Tab.  If pressing Tab without selection, it will just insert a tab at the cursor, which is not what you want unless the cursor is at the beginning of the line.

To decrease indent of the current line:
Shift + Tab.  No need to make a selection

To auto-format the current line:
Command + W, then Command + Alt + L.  Without a selection, it will just auto-indent the whole file

To auto-indent the current line:
Command + W, then Command + Alt + I.

To join next line into the current line:
Ctrl + Shift + J.  Useful when you need to get rid of the next few blank lines.  Command + Y will also delete a line, but you will need to move cursor to the blank line first.

To go to the beginning and end of the file:
Command + fn + Left
Command + fn + right
