Hi Joanie:

I understand your point now, and you made it clearly, thanks.  I think 
it comes down to how one uses the orca modifier or shortcuts.  If one's 
orca use is highly "modal", i.e. one tends to stay in "orca mode" or 
"pure keyboard mode", then the latching behavior of ShiftLock could be 
an advantage, and I agree that it would make a useful modifier in that 
scenario.

On the other hand, if the user model is less modal, and the user is 
frequently interspersing single orca commands within a stream of 
"normal" application keynav, the ShiftLock latching behavior would be a 
big annoyance.

I think that flat-review tends to be "modal", i.e. you're either in 
review mode or you aren't, where as many of the other orca commands may 
be less so.  I'll leave it to the orca designers and users to figure out 
where the balance lies.

If you do find that some features are rather modal, there are two other 
latching keys available on many, but not all, keyboards, including 
laptop keyboard - NumLock and ScrollLock, so they may end up figuring 
into the discussion as well; in my experience NumLock can be either Mod3 
or Mod4 in the Xserver modifier mask, depending on the X server 
implementation. (I am not sure ScrollLock actually appears in the 
modifier mask at all)

regards,

Bill
