I want to be able to change the behaviour of double click to select a single word when underscores are used as word separators. Currently if I double click `this_is_a_test` in geany the whole entire sentence is selected. I want to be able to double click and select only the words in it. This isn't a problem for dashes `this-is-a-test` double clicking any word in this test selects only the word. I read through #492 but that seemed to be for keyboard interactions not mouse interactions.
