I am new to home designer software, and installed Interiors product to test it out. I am noticing that there is no mention of a key combination in the menus to scroll a plan (that i am viewing) up or down. I have to reach for the mouse and move it and then move the scroll bar. Usually, there is a key that one can hold down, while using the wheel on the mouse in order scroll something up or down (like you do in browsers). But, SHIFT or CONTROL or ALT key holding down does not activate this easy to use scroll-wheel of a mouse. So, if you have a big plan that spans multiple pages (and you do not want to use the zoom feature, for whatever reason) then the only option is to reach for the scroll bar. As an experienced computer pro, i find this irritating lack in a sophisticated software product. Am i missing something ?? Is there a way to do what i want ?
