Your post raises another question I have yet to find and answer for: how do you make an "enyay" the "n" with the "tilda" over top of it? Is there a comand that does this or do you have a different key board?
One way you can do it, if there happens to be one on the screen already, is just to block and copy it ... ñ <- I took this one from opiñonista's post
(you know you can just highlight it, then Ctrl-C, then move cursor where you want it, then Ctrl-V)
Course that only works if there happens to be one on your screen at the time.
There is also a combination of ALT plus some 3-digit numeric code that will often but not always work. e.g., it's not working on my keyboard right now ...
I think it only works with a number pad? The codes for the usual Euroextra letters are in the range of about 130 to 160. Alt-130 is "e" with an acute (bottom left to top right) accent.
