Many thanks for taking time to respond to my post.
The macros don't run???
I'm stumped…I tested them (prior to posting here) under varying conditions and they worked as intended (I was a software QA analyst in a previous career).
I did not observe the outcome that deleting a file selected in the Finder resulted in the immediate emptying of the Trash. In fact, I did that with a number of files yesterday afternoon using the keyboard shortcut and the files are still n the Trash (I opened its window in the Finder using Go>Go to folder… to confirm).
And for good measure, I just tried it again and the file went to the Trash without the Trash automatically emptying.
Maybe this discrepancy in our observations is due to my having both macros in a group which is configured as a palette, and you don't??? As such, the palette has a single button which toggles between the two icons—Trash full, Trash empty—which are assigned to the two macros.
Regardless, many thanks also for teaching me for how to open the Trash folder. Now I can add that feature to the palette's button(s).
