      Thanks, Eb. This is similar to the clip I wrote except my clip creates a temporary new doc to work in and fills the screen with text. An issue with your code is that the number of rows is not correct if there are less than a screen full of rows since I want the maximum number of rows that can be displayed (screen size) and not the number actually displayed. In other words, if 20 rows can fit and there are only 10, your code will report 10 instead of 20.

      In other words, I guess there isn't a direct way of doing this.
      Another idea for the enhancement list!

      Also, for beginners following along, the corrected lines should be
      ^!Keyboard CTRL+PAGEDOWN
      ^!Set %bot%=^$GetRow$
