Hello,

How can I make it look like this again?

I do not know what option should be selected to show me again as it looks in the 2nd image …
What option must be selected to change Null inside the functions?

Thank you.

It is difficult to second-guess output without having the actual input.

I think it’s more from some settings from Edit > Preferences > Advanced > Option Inspector, because I enabled several options there, but I don’t know which one anymore, and how to make it show me back/suggest mathematica the parameters of the function that must be put into the function (regardless of what wolfram mathematica proper function it is)

Enable = True

5

Maybe it’s somewhere in Editing Options > Private Editing Options > CodeAssistOptions.

I’ll look tomorrow to see, but I do not know which option I set True there (in Option Inspector)

Can someone check if this thing happens to him too?
What he/she has to do is this: to write this line in mathematica
Plot then press enter and then press [ and then press ]
And he/she should see that: Plot[Null, Null, Null]
