Thank you Fred
I should have read help on the keypress event :-(

The use of nShftAltCtrl is to help identify the difference in key values:
For right arrow, the nKeyCode=4 and the nShftAltCtrl=0
For Ctrl+D, the nKeyCode=4 and the nShftAltCtrl=2
nShftAltCtrl:
0 = no modifiers.
1 = Shift
2 = Ctrl
4 = Alt (Note that you usually can't trap the Alt key press using this)
The above values are summed if 2 or more are pressed, so Shift+Ctrl would
be 3. Again, Alt does not work in most cases.

I haven't used on key labels since the days of old FoxDOS.
However, I am migrating an old FD app to VFP9 and the prgs include a
zillion on key labels operating on browse windows.
I easily replaced all browse windows with grids and the on key label calls
with calls to the keypress events of the corresponding text boxes.
However, there is one particular on key label that is driving me nuts:
on key label ctrl+D do form frmDelete
In the keypress event of the textbox of the corresponding column of the
grid I wrote:
lparameters nKeyCode,nShiftAltCtrl
if nKeyCode = 4 && ctrl+D
do form frmDelete
endif
But to my surprise, the same number (4) is assigned to the right arrow
key, so when the user navigates the grid with the right arrow, the
frmDelete form pops up, as if he had pressed the Ctrl+D key combination
How can I solve this?
The numbers can be seen in help for the inkey() function
BTW, I never used the second parameter, nShiftAltCtrl of the keypress
event. And can't figure out how to use it.
