# How to disable the small pop-up windows when mouse is over a Mathematica command in V10?

In version 10, when the mouse is over a Mathematica command, a small pop-up window comes up that one can click on for help on the command.

Is there an option to disable this feature? Screen shot:

I tried number of options here, but no effect. It must be in the advanced perferences? But not sure what to look for.

Update:

Thanks to Martin answer below. These options can be changed permanently in advanced options

I also turned off the "ShowCodeAssist" just in case

Unfortunately I cannot claim the original discovery, but there are additional CodeAssistOptions in M10, the one you want is:

SetOptions[EvaluationNotebook[], CodeAssistOptions -> {"FloatingElementEnable" -> False}]


You could replace EvaluationNotebook[] with $FrontEnd but I prefer not to change $FrontEnd options.

You could use $FrontEndSession to make it temporary – Mike Honeychurch Jul 10 '14 at 0:35 @MikeHoneychurch I'm an unusual user, I need it to show in most all my notebooks but in a small number I never ever want it to show. You're right, for most people $FrontEndSession would be the way to go. –  Martin John Hadley Jul 10 '14 at 10:15

For what it's worth, the accepted answer does not function in the Raspberry Pi version of Mathematica. A slight change gets you the result:

SetOptions[EvaluationNotebook[],"ShowCodeAssist"->False]


This is particularly helpful on the RPi since the code assist links attempt to find the nonexistent documentation. [The RPi does not ship with documentation and users must go to the web for references.)

This also removes the code-completion assistant, which is otherwise helpful during typing. Is there any way to have the completion floater but not the mousover floater? It seems like I either have both or none (or only the mouseover floater but not the former). (Mathematica 10.1 Win7) –  István Zachar Apr 21 at 14:10
@IstvánZachar I don't know the answer to your question. I've only explored the issue on the RPi, and for my purposes, having neither autocompletion nor mouseover was the best scenario. –  bobthechemist Apr 21 at 17:23
@IstvánZachar you can trigger code completion popup by pressing <F2>, at least on Linux/Windows versions. –  Ruslan May 4 at 6:50

The popup window you are talking about is removed by the ShowCodeAssist option set to false. The other settings don't concern your problem.

On can also use the menu bar. Go to Edit ▶ Preferences... and under the Interface tab one can uncheck "Enable floating elements ..."

Alternatively, one can increase the delay to a number that is big enough to prevent an unwanted pop up.

I can't find this option on Mathematica v10 on Linux –  JeffDror Jun 9 at 16:53
