There is one way that is acting similar to a "grab": Put the following
into your card's script. Works for widgets and any 'usual' control that
doesn't block mouseDown.
if the short name of the target is "svgTURTLE" then # <-- use any filter
put the mouseControl into mC; put false into mUp
put the clickH - item 1 of the loc of mC into dx
put the clickV - item 2 of the loc of mC into dy
repeat until the mouse is up
set loc of mC to (the mouseH-dx,the mouseV-dy)
Using a "send in time" is not possible for that, because the click is then
passed 'in between' to the control/widget. You sadly have to poll the mouse.
