I'm having trouble rolling my own MouseKeys program - when a key on the numeric keypad is pressed, it does not generate the expected key code and flags, according to the low-level keyboard hook procedure.
For example, on pressing 0, a keycode of VK_INSERT and flags without the extended flag set, is generated, rather than VK_NUMPAD0 with the extended flag set (or at least that is what I think should be generated). On pressing 1, although the keycode is VK_NUMPAD1, the extended flag is not set. Numlock makes no difference whatsoever.
And I still haven't been able to figure out how to recognize the Period/Del key.
I'd like to keep the arrow keys for cursor movement, the insert and delete keys for left/right mouse buttons, and the plus key for the middle mouse button.
I've attached the result of my struggles.

I think you'll have to check the actual status of num-lock and then act accordingly, rather than relying on the 'extended' flag.
I've finally figured it out. The seeds of my confusion were:
1. Misleading MSDN documentation. Contrary to what is mentioned, the extended flag is not set when a key on the numeric keypad is pressed, irrespective of the status of num lock. Instead, the extended flag is set when the "stand-alone" insert, delete etc. keys are pressed.
2. My assumption/expectation that the virtual-key codes for the printable character keys are the same as their corresponding ASCII values. This is not always true for the "overloaded" keys. For instance, the >. key generates the keycode 0xBE, rather than 0x2E. Incidentally, 0x2E is the keycode for insert. I wonder why they had to do that. ::)
Anyway, I'll fix my program now.
Whee! :dance:
Now all I have to add is speed control and pause/stop features, perhaps with a nice front-end.
Edit: Fixed a bug.

Would have finished this sooner, but got caught up with other stuff.
Anyway, although I managed to put in all the features that I had originally planned for:
- Speed control of cursor keys, and speed "blending" with Shift, Ctrl and Alt keys
- Customizable "action" keys
- Command line options and single instance operation
I could not implement (at the code level) the blending operation the way I wanted to, due to some peculiar Shift key behavior.
Annoyingly, I can't seem to get the visual styles to apply.
