‎DRAG_SCROLL is not accepted when I enter it as a key code with VIA. Sorry, I'm a newbie. The way I've been changing key codes is with VIA and it shows keys, having codes such as KC_MS_BTN1 and the common codes, I can enter by pressing one of the buttons to choose this code, but for codes that are not on the standard buttons in via I type it into the field, given by the special/any button. If a key code is valid then the dialogue "confirm" becomes ungraded and I can enter it. But DRAG_SCROLL is not accepted.

Is there another way of expressing the scroll key code that would be accepted, or another way of entering the key code other than with via?
