1.2.11: possible bugs

There are some possible bugs, which I also noticed in a few previous versions. Maybe some light could be shed on it:

• Pressing Enter for Edit/Rotate/90CW (menu) does not execute expected action; must press L-Clck; pressing Enter also seems to do something else, but I forgot this little detail (looked like it was doing something with some options if something is selected with Marquee Tool)

• Gradient Tool, upon L-Clck within desired constrained area, draws outside of it, if starting near side/border of desired constrained area;

• Alt + Clck does not pick color, but picks Mask; happened after Paint Bucket Tool was used, but probably in some other cases too;

• Often, if L-Clck after Keyboard Btn, no immediate response.
