Some of the mouse commands that are listed in the manual are difficult for 
Mac users, since we don't generally have 3-button mice and a control-click 
is the same as a right click (we'll leave the trackpad out of it).

That said, I was working on a mask and found some inconsistencies with what 
the manual says, and just some oddities. Are these actual bugs or has the 
manual simply not been updated? I'm happy to create a screencast to show 
them, if that would help.

   1. A right-drag inside a mask does what the manual says and moves it. 
   (Control-click and drag acts the same, as expected.) So the hint about 
   command being the same as control on the Mac is wrong here. The only issue 
   I found is that sometimes it takes a second for Hugin to register the click 
   and select the entire mask.
   2. OTOH, command-clicking on a line creates a new point there, just as 
   control-clicking is said to for other OSes.
   3. When I click on an existing point, Hugin will sometimes select not 
   just that point, but also an adjacent one or more. Why?
   4. When I click *near* the mask, Hugin will select 1 or more points. 
   They look like the closest n points to where I'm clicking, but how is it 
   deciding what n is? This looks like Hugin treats a click *near* the mask 
   as if it were actually *on* the mask. Note that unlike #3, the points do 
   not have to be adjacent to each other, but apparently near to the click 
   location.
   5. Similar to #4, if I command-click somewhere *off* a line, Hugin will 
   create a new point, but not necessarily in the nearest line segment. How is 
   it deciding where to make the new point? I can actually get pretty far away 
   from the mask and have this happen.
   6. Drawing a marquee around a point will sometimes select adjacent 
   points as well, just like clicking does. This is somewhat dependent on the 
   size of the marquee: a small one confined to an area just around a point 
   will select only that point, but if the marquee is big and approaches other 
   points - even if it doesn't include them - then more than one point will be 
   selected.
   7. If I drag a point selection (of one or more points) a short distance 
   away from its original location, it will snap back. But if I drag it 
   further, it will stay where I put it. What's happening there? Is there some 
   minimum change that Hugin needs? (If so, that's not very helpful for 
   tweaking masks.)

Any help appreciated. I'm happy to file these as bugs, but not if I just 
need to RTFM (whatever manual that is).

Thanks.
