I have a project for uni to do in which I need to make a dictionary out of the words I don’t know from a book. I have the file but when I use okular I can’t highlight words fast, by fast I mean double click the word and then with a shortcut or a button to highlight the word and move on, or to double click while the tool is selected and the whole word to get highlighted, I have to drag my mouse every time I want to highlight a word and when you have to do it repeatedly it gets annoying I know it’s a minor thing but if there is a fix I would like to know. Thanks in advance.
