Annoying little things

[oldtima]

Can the authors please make PgUp and PgDn relocate the cursor within the code by one page the way the Up and Down keys do line by line?

Same thing applies to shift-arrows and shift-pgup/pgdn/home/end in the memory dump. Us old-timers hate being forced to use the mouse. Thank you in advance! Wonderful tool! I wish I could contribute.

Also, editing the instruction containing an int3 breakpoint doesn't modify the first byte.
