More than 50% of that 4-5 seconds is the AppleScript "application" launching.I wonder if it is the application launching, or the control panel.
It's almost all AppleScript.Do you know if the bulk of that [memory usage] is EZ-Keys? Or AppleScript.
If a knowledgeable person were to write a one-trick pony Extension in Assembly language that would put selected items into the Trash when CMD-DEL is pressed, that would likely be the smallest and fastest solution. But patience is a virtue, and for now, the AppleScript 1.1 + EZ-Keys method does work.
