[Closed] Sticky keys (keyDown) in Max ??

is there any way to implement this in max out of SDK ?
i’m referring to those functions found in editable poly where you can hold the key down and keep holding it to invoke a function .

All I can think of is a .netform having the focus … but that would defeat the whole thing !

a good Example is … hold a key down … walk in the viewport …release the key … stop walking (that function is already in max , its just an example)
