Autoclicking software

Good luck.
you can’t use autoclicker while you’re killing the boss as an example, but if you just stay and open the boxes – no problem. You don’s need any autoclick software, just put multiple doubleclicks on 1 button or something like that.
The only clear thing ANet have said on this is one key-press = one action. Most people seem to settle on binding mouse wheel to double-click as each click of the wheel results in one action. However ANet have never said if they are happy with this or not. Some people prefer to suffer pain and injury playing the game than take the risk of an account ban. A better designed game wouldn’t require you to injure yourself to play it!
From my understanding using a Macro for this is NOT ok (techncially), but it is doubtful Anet would notice it or care (as long as you aren’t using it outside of inventory actions. Keep in mind this is MY opinion and I don’t think enough of it to take the chance of a ban and do it myself.
One option that I have heard others use is to use mouse software to bind the click action (one action) to the mouse scroll wheel (or other scroll wheel on a control pad, etc.) and then you can simply scroll the wheel to use a lot of items….this should not violate the one key = one action policy. Note I have never seen any official “that’s ok” for this method either, so use the information at your own risk.
Fate is just the weight of circumstances
That’s the way that lady luck dances
A right-click menu “Open all” should be enough…
I think binding double click shall not be a problem. For example tablet pen from Wacom Intuos 3 uses double click macro as a default setting and that’s pretty much standard hardware. Okay, it isn’t designed for games, but digital painting, but it’s still standard function.
And I do agree with post above me, right-click menu “Open all” would be more than enough.
