Okay, thanks. I tried `\approx + tab + go 1 back + \not + tab`
It gives me the same thing as `\not + tab + \approx + tab` on ubuntu with both atom and jupyter. It gives me something that does look roughly but not exactly like ≉. I think it is two symbols on top of each other, a slash thingy and ≈. Anyway julia does not like it: ` LoadError: syntax: invalid character "̸" while loading In[38], in expression starting on line 1 ` On Friday, June 3, 2016 at 10:16:21 AM UTC+2, Jutho wrote: > > (on Mac): what seems to work is to first use \approx + tab to get ≈, and > then go back one character and type \not + tab.
