Python program that allows for keyboard abbreviations from a .json file.
Originally designed for use in LaTeX note taking (minimising hand reaching and shift and arrow pressing), but can be used for other purposes.
With the default LaTeX abbreviations, one could type the quadratic formula like this:
Original LaTeX: x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}
Abbreviated version (arrows in square brackets): x=fr -b+-sqrt bex 2[right]-4ac[right][right][right]2a
