|  Re: Commodore 16 vs 116 - keyboard layout different - is possible to detect between?
You're asking for something that isn't possible. The 264 series is NOT built like the 64 or 128.
Here's a picture of the 264 series (16, 116, 232, 264, V364) keyboard matrix:

You can see from that matrix that there's only ONE Shift key, from the keyboard's point of view. What you find as the right shift on the C64 is the Escape key on the 264 series.
Detecting between Shift and Shift Lock is not possible on the 264 series either. Either a shift is pressed (or locked) or it's not. The link above shows that the Lock switch mechanically connects column 2 with row 7. See this photograph and count the Shift keys, you'll understand why. ;)
