Hello Joey,


you have to hold down CTRL and press . (in shortcuts in general + is a chaining symbol for who reads, not something to press)
If you like my plugins please consider to support the program buying a license; for personal contributions to me: paypal.me/dcprojects

Simple differentiation, Ah ! Sometimes not so simple, example: erf(x).
Please, visit this work sheet, worth the time spent .
