This is a thread hijack!
I wanted to reach Cetin.
I made a mulitselect class from your gridx.zip code.
I added these keys to select ranges:
    Shift+PageDn,PageUp
    Shift+Home,End
In my version, I moved the code from the textbox to the grid.
You will need VFP 8.

Would like a copy of this class?
