Notepad++ has a convenient feature: if you select a word in your text (not necessarily a keyword), the word is highlighted throughout the text. Can this be done in Emacs as well? And if so, how?
It doesn’t necessarily have to work exactly like Notepad++ (i.e., via selection); ideally, I would like to set up a key binding that causes all occurrences of the word under cursor to be highlighted.
It would be great if the highlights were permanent, i.e., moving point away from a highlighted word should not cause the highlight to be removed.
Also, it would be useful if there was a solution that made it possible to navigate between highlights (using custom key bindings).
