Andrus,
It's normal Ctrl+E and uparrow have same values. Ctrl+E,X,S,D would give arrow movements, Ctrl+M enter, Ctrl+[ Esc, Ctrl+H backspace, Ctrl+i Tab etc. I think this due to old times where you should do this movements with ctrl keys on a terminal emulation. In form.keypress you could intercept it so you may want to move code there (with form.keypreview = .t.).
145 is for Ctrl+DnArrow and in my class is used for adding a new record. When pasting the code I only pasted that part and missed my extra key was there too.
