I use a tiny mouse on the left front of my laptop (being left-handed) and have to be so careful not to have the mouse activate the touchpad! I also have a bad habit of having the front of the mouse stray onto the Windows key and the Alt key together - which, as alt/windows is a non-existent command, crashes the whole thing. Every time.

I just added all the names, with their accents, to the dictionary on Word on my laptop by copying and pasting them in from the Encyclopaedia of Arda, adding them to the dictionary, then typing them spelt correctly but without the accents and instructing it to then auto-correct to the newly added version every time I write them. It wasn't all that long-winded.
