As a "function" key, F9 can be mapped to perform any task, depending on the program and operating system in use. Common uses include controlling brightness or volume (on laptops), controlling the BIOS setup program, or switching between terminal displays (Unix / Linux).

There is no single answer to that. Different applications use it for different actions and some may not have a use for it at all. For some it is used to update the particular instance relevant to the application, like recalculate formulas or update fields. In addition to F9 itself, it can be used in conjunction with other keys - like Ctrl, Alt and Shift - to do other actions.

It updates fields in your Word document. Use "CTRL-A" to select the entire document, and then hit F9 to update all the fields in your document.

Does Pressing the F9 key instruct Excel to recalculate all formulas?

When you are working in Manual Recalculation mode, that is what it will do. For Automatic Recalculation it is not really used, as formulas will update any time a change is made. Pressing F9 will still recalculate them, but there is no need to. There are a few exceptions where you might use F9 when Automatic Recalculation is working. You could use it to regenerate values for the RANDBETWEEN function for example.


Can you redraw a chart using f9 key when you change data?

Charts will automatically update themselves when data is changed, so there is no need to press any key. F9 is used to update a sheet that has been set to manual calculation. When it is in operation, pressing F9 will update the data and as a result the charts will change automatically.
