How restore condition after using JS snippet

Hi,
I used a JS snippet “Add a second slider button” for Sydney Pro theme (I’m using on child theme), using TC Custom JavaScript.
Code is:
"jQuery(function($) {
var myButton = ‘My Button’;
$( ‘.slide-inner’ ).append(myButton);
});

Now I don’t know how remove that code and turn back previous situation.
Many thanks.

Dear Alfo,

Please go to Appearance > Custom JavaScript. Then remove that code. Have you done this?

Dear Kharish,
yes I did, but it’s impossible to delete code (is shown always), maybe is a plugin’s bug?
In this case, where I could remove that code manually?
thanks
Alfo

Kharis…I resolved…using “delete” from menu on right click mouse and not with “delete” key from keyboard.
Now code is deleted.
Thanks for your disposability.
