I never really liked Dragon's scroll commands:

Automatic scrolling -  "start scrolling down/up",  "stop scrolling",  "scroll faster/slower"

Let alone the IMHO stupidity of having scroll up/down go to the top/bottom of webpage!!!

Moreover, much the time when I need to scroll I'm struggling 2 dimensionally, e.g. in a map or in a very big OneNote page or table or spreadsheet, scrolling both up/down and left/right and combinations of the above.

I am embarrassed to admit how much time I wasted writing such commands.

Embarrassed, when I was reminded about Windows "middle click scrolling",  i.e. mouse/trackball displacement scrolling.  Type or press the most middle button -  on my trackball pressing the left and right buttons simultaneously -  entering a mode where stall speed is controlled by how far you have displaced the pointer from its original position, with  a visual indication of whether you can scroll in 1D or 2D.  

I am fortunate in being able to  interact with my PC using both Mic+Mouse.  Actually Mic+Trackball,  since moving a mouse aggravates my computeritis.  i.e. I can move the mouse/trackball pointer fairly easily using my noninjured hand, and I can click  the four trackball  buttons fairly easily.   but I don't like clicking the trackball buttons if I can avoid it.

So now I just have a speech command "DRACO scroll mode"  that enters this middle click  scroll mode. 

IMHO this scroll mode is far better than the Dragon builtin  automatic scrolling, because it is smooth, not jerky, not a line or character at a time.   much easier for me to read as it scrolls by.

The biggest problem with this scroll mode is that it is not supported by all apps.   In fact I am only actually enabling the middle click  scroll mode speech command in applications and windows where I know it will work, because sending a middle click in inappropriate places like emacs can be quite damaging.

Q: does anyone have a list of apps that support middle click scrolling?     

At the moment if I am not in such a known good app I have "DRACO scroll mode"  emit advice "Warning: mouse scrollmode does not work in all apps", with a MsgBox showing what to change to make it work in an app where actually does work but my speech command does not yet know.   It would be nice to have a pre-populated fairly comprehensive list such apps.

I do not have the scroll mode command fall back to Dragon's default  automatic scrolling, because I dislike the latter so much that I would rather manually move over to the scroll bar if it exists..
