I am typing in Spanish.

I want to type, e.g., "nino" and "bebe" with a tilde over the letter "n" and
an acute accent over the letter "e".

I can type a tilde in Word (sometimes -- it usually does not work) by
pressing down simultaneously: CTRL + SHIFT + ~ (TILDE), then letting go of
those keys, and then pressing a lower-case "n".

I can type an acute accent in Word by pressing down simultaneously: CTRL +
Apostrophe, then letting go of those keys, and then presseing a lower-case
"e".

These shortcut combinations do not seem to be working in *Excel*.

I can also (in both Word and Excel) use Insert = Symbol = Symbol tab, and
then select the symbol I want, but this is very slow.

I prefer to use a shortcut key, rather than insert a symbol, because the
shortcut key method is much quicker.

Can anyone help me out?

Thank you in advance.
