I know this is barely a craft, but I had to record it somewhere before I forget (since editing the ‘tips’ section of my website is too difficult… must remedy this in the future).

I was getting incredibly sick of Word putting the line break in the middle of my exponents. For example:

… rates of 3.0 kmol N d^−
1 and other…

So I learned about the “non-breaking” dash/minus sign, unicode character 2212.  To insert it, type 2212, then press alt+x to replace the 2212 with the symbol.  I then ctrl-h’ed to replace all of them.
