I find it awkward to enter negative fractions in Mathematica when using formula mode. For example I need to enter $ -\frac{1}{12}$ in a text cell. I would press 7 to enter text mode, then ctrl9 to start inline math cell (aka formula mode), then press -, space and ctrl/ to start the fraction input.

However instead of showing me two small empty boxes for the numerator and the denominator, Mathematica places my - character inside the numerator box. To work around this, I have to type in a positive fraction with ctrl/ first, then exit the fraction mode with ctrlspace, backtrack to before the fraction and insert -. Is there a more efficient way to enter negative fractions in inline math cells or in input mode?

I like to use expand selection (ctrl.) to do this. For example:

-, 1, ctrl., ctrl/, 1, 2
