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.
