[EDIT: trying again - the Dropbox links are for the most current version!]
If you want just the application you can get it from my Dropbox:

If you want the entire Microsoft Visual Solution 2017 solution:

Screen Grid (ScreenGrid.exe)
I've written a multi-monitor aware replacement for Nuance’s Dragon utility "Mouse Grid"; released as public domain as a Microsoft Visual Studio 2017 C# project. The application creates a semi-transparent window the size of the entire multi-monitor screen (regardless of the monitors’ arrangement); a grid is drawn with a maximum of 26 columns (labeled with the ASCII letters A-Z) and 10 rows (labeled with the ASCII numerals 1-10). Each cell is labeled with the column letter and row number: A1-Z10.
The attached Readme file has all the new details.
