Linux Editor that can highlight all instances of a selected word [closed]

Question

Is there an editor in Linux that can highlight all instances of a word when the word is double-clicked? I was using Notepad++ in Windows which provided that feature. Now I am missing it in Linux editors. I tried Kate, Gedit, etc.
