In reply to Ian Parsons:
> Cheers Gordon - I'll check that out. (I have to confess I have no idea what it is!) Meantime, I've discovered that Alt 0234 works if the number lock is on - Arête; bingo! - but am still puzzled as to why that isn't necessary for 0232, 0233, etc. There are, however, many workings of this thing on my desk that I don't understand.
Ditto. Although I am a web designer, I only understand at the level of 'how to do it', and only vaguely the 'why'. There is a huge amount of geekdom involved. Re. the code I gave above, I should have said miss out the spaces. There are two main types of code to use for symbols in web design, those starting with an ampersand followed by some letters plus a semi-colon (an "entity" reference) and those starting with ampersand, a hashtag, a number plus a semicolon (a "numeric" reference). I know that the former are considered passé, if not deprecated, while the latter are always to be preferred. Beyond that, let's leave it to the geeks, who are doing a splendid job in making everything work 'under the bonnet'.
