To get the keypad to work in Vim you need to configure PuTTY to ignore the application keypad mode.
1. Go to settings->terminal->features in PuTTy
2. Check the box labeled “Disable application keypad mode”
3. Press ‘Apply’
4. In Vim make sure numlock is on and then start typing numbers
If you forget numlock the keypad will be used for cursor movement
Tested on PuTTy v0.60
