I'm not sure what F9 does in Excel but by very quick check it seems to be a shortcut for some recalculations. You can recalculate formulas from red triangle of the table name and using Rerun Formulas.

For singular formula I think you might have to open the formula editor and click Apply.
If you have ideas of features you would like to have in JMP, you can make a post to JMP Wish List.
