Wanted: KB shortcut to Calc Name Box

In Calc I would like to set F3 as a KB shortcut which moves the focus to
the "Name Box" (1st control on formula bar). This would provide navigation
equivalent to a 'go to cell' command which would be useful for my very
large spreadsheets (without having to reach for the mouse). I don't see an
option for that under Tools > Customize > Keyboard. Does anyone know if
such a KB shortcut can be set?

It already exists:

<Ctrl><Shift>+F5 or <Ctrl><Shift>+T

But if you want to use the F3 key it is available to be assigned from the
Customize dialog, Keyboard tab

Function -- Sheet Area Input Field

Regina & Stuart, Many thanks. I did not expect the name of this function
to be "Sheet Area Input Field". The ease and flexibility of creating LO
Keyboard shortcuts is an outstanding feature that enhances my
productivity. BH
