I would like to know how I can change my take all button from A to the enter key. I figured out how to do it to a different letter, but It will not do anything else for me but the letters.

Albeit, there's not currently a ClickMenuButton for NVSE...

scn NonPlayableQuestItemTokenObjectSCPTBegin MenuMode 1008 ; Container/Corpse	If IsKeyPressed 28 ; Enter		ClickMenuButton "#10" 1008 ; "Take All"	EndIfEnd

...should work if you can twist the NVSE team's arm for the ClickMenuButton function.

Thanks Justin!
