[jawsscripts] Re: Does any event trigger when you use the quick nav keys?

Also use a variable that determines if quick nav keys are activated.
There is a function and a flag for this, so run the function in FocusChangedEvent to set or unset the global flag, then use that flag as your first step in the condition statement in KeyPressedEvent. That makes it less intrusive on regular keypresses. Also check for FormsMode flag in that same condition so it doesn't activate if entering text in a form field. 

Thanks,
Dennis Brown

You should insert some logic into KeyPressedEvent to make sure your
logic needs to fire, not just fire your logic every time this event is
fired. So you would want to check for:

(1) Is the nIsScriptKey parameter variable TRUE or FALSE? You only
want to proceed if it is TRUE.
(2) Is the Virtual PC cursor active? You should proceed if it is TRUE.
(3) Is the KeyPressedEvent being fired from a quicknav key? You will
need to write a function to determine if the current script key is a
quicknav key combination. Note: use the length of the
GetCurrentScriptKey function's return value, along with StringSegment
using the plus sign (+) as the delimiter.
(4) If all of these conditions are met, fire your logic, otherwise, return. 

Using the order I listed above minimizes overhead, since you are
proceeding in the order of operations that use less memory up-front.

This won't work though, the script checks for a condition by querying
elements on a web page, then when the condition is found, a variable object for the DOM is stored, and a scheduled event runs to check on the condition 
of a specific element every two seconds.
If this script were triggered every time a key is pressed, it would be way 
too intrusive and would degrade performance.

It does work if I attach the script to the main navigation commands like
prior line, next line, paragraph, etc., but the only condition that gets
past the script handler however, is when the quick nav keys are used to jump 
directly into a form element, which doesn't look to trigger any sort of
event like FocusChangeEvent, or FocusPointMovedEvent.
If there isn't a basic event handler for this, then I guess I'll just have 
to attach key assignments to e and f to check for the condition, then
continue on to the quick nav command. It's a bit clunky like this though.
