Quest turning in/picking up at same time

Was wondering if it was possible to get/pick up quests at the same time with all my toons. Was messing around with the repeater but I could not get it to work. Think it may have to do with my window layout. As some of the windows were getting it at the same time and others were not.

Saw a video of Lax doing something like this on WoW, but think it was WoW specific, I cannot remember.

You can bind this to a key: F10 -> all
U-> all
\ -> all

Binded to my ` key. This selects the nearest npc and interacts with them. If all your windows are the same resolution you can turn on the repeater to get or hand in quest at the same time. Usually I just get my main toon to get the quests then share then use the mouse repeater. You can also use this to loot(make sure to have loot all on). I use a similar one to farm resources so I don't have to click on the resource node or change toons.

Duh, Ill use the main toon idea. Thanks
