An extremely useful thing to know in emacs is how to discover what keys are bound to which commands on your own. 

If you know the name of the command -- goto-line. If you type 'C-h w' (Control+h and then w), Emacs will as you "Where is command: ". Type goto-line and hit enter, and it will tell you what keystrokes (if any) are bound to that command.

There are a bunch more similar features. 'C-h k' does the inverse -- asks you for a keystroke and then tells you the command it runs; 'C-h b' shows all current keybindings; 'C-h a' will search for a string, so you might type 'C-h a goto' to search for commands with "goto" in the name; 'C-h v' describes variables; 'C-h f' describes functions; etc.

To keep Excel from dynamically moving the target range for a function, use the $ in front of the col and row references.

On a windows machine, you can toggle through the "lock down" methods with the F4 key.

A '$' will lock down the reference to an absolute one versus a relative one. You can lock down the column, row or both. Here is a locked down absolute reference for your example.

(A1-MIN($A$1:$A$30))/(MAX($A$1:$A$30)-MIN($A$1:$A$30))
