>>Sergy,
>>I only want to detect if the shift key has been pressed by itself. Your sample is good to determine if I want SHIFT + U (UPPER"U") or SHIFT+F2. No other key combinations necessary. The VFP keypress will not detect a loan shift keypress. The keypress event on the VFP form will not fire if I only press shift.

I believe the keyboard does send interrupt signal for key press and release the "shift" type keys (e.g. SHIFT, CTRL, ALT) and are processed in the BIOS. IIRC you can query the state of shift keys with BIOS calls back in the DOS days. I'd think a similar feature is still available in Windows -- isn't there a shift/alt/ctrl combo that is used in Windows to suppress autorun for removable disc?
