To reproduce:

1. Click the SFX number of an SFX
2. Push Ctrl/Cmd + C to copy the entire SFX
3. Use the keyboard to move around to some note(s) and select them (with shift)
4. Push Ctrl/Cmd + C

Expected Result: the selection which was just made with the keyboard will be copied
Actual Result: the entire SFX is copied, because only the mouse's last focus is respected, not the keyboard's

(I always hope that he searches the forum for callouts to his name.)

looks like this is still present in 0.1.12c

I just came to report this too.

Selecting a block of notes using shift + arrow keys and then doing copy, does not copy the notes in the same way as selecting the same block of notes using the mouse.
