[orca-list] Understand better Orca keys for Firefox

[Luciano de Souza <luchyanus gmail com>]

Hi all,

Orca offers advanced features to navigate with Firefox. However, since I 
couldn't understand the usage of some keys, I am not able to use Firefox 
and Orca appropriately. I am persuaded it's not enough to know the keys 
combinations, it's necessary to understand the situations when we should 
call then.

Pressing "d", we can move the cursor to the next dynamic region. But, 
what is exactly a dynamic region? If I am navigating away, when should 
I  remember it would be a very good idea to press "d"?

A dynamic region seems to be an area whose content changes automaticly.

With insert+F1 to F9, we can monitore dynamic regions. But, if there are 
nine positions available, I can presume it's necessary to assign each 
region and, later, to monitore then with the mentioned keystrokes. Well, 
I really didn't understand what is a dynamic regions and when I should 
assign or  monitore then.

My second doubt is about gecko cursor. Pressing insert+F12, we can turn 
between  gecko and Orca cursor. If I correctly understood, the Orca keys 
work only when Orca cursor is enabled. However, if gecko cursor can be 
chosen, I presume, in certain situations, the best result is obtained 
with Gecko cursor. When does it occur?

Pressing "m", we can move to the next mark. But what is exactly a mark? 
Pressing it when navigating in a certain page, I was moved to the first 
editbox.

Reghards,
