Sublime Arithmetic Editing = Magic
This Sublime Text shortcut saved my day: Evaluate Math Expression.
I had a CSV with hundreds of time values in 12hr format I needed to convert to 24hr format. Instead of lots of manual editing, I was able to use a shortcut made possible by Emmet. Simply add your math expression, highlight it, and hit command + shift + Y. Voila.
The true magic begins when you pair it with Sublime’s multi-select shortcuts.
Thanks to Tommy Marshall for the clear example!
