Problem solved, mostly - I rewrote the function to calculate the distance between each two successive points, and if the distance is less than some threshold, the function ends. By double-clicking while digitizing, two colocated points are generated, ending the loop. This method works, mostly, but is a little bit unreliable. If anyone has a whizzy widget version, I would love to hear about it!

Pardon my ignorance, but how do I use the command line version vs. the Workbench (?) version I am using?

A quick test shows that get_kbrd() works just fine using the command
line version of IDL 8.1. I tried it on Linux and Windows. So, your
old routine would probably work that way.

Furthermore, attempting to use this function caused IDL to become unresponsive, and I had to exit and restart IDL. I could type commands in the console and IDL would echo them, but nothing would happen.
get_kbrd(), as far as I can tell, is completely broken under
Workbench. (The documentation says "use caution when using GET_KBRD
within a loop.") It's a shame, because it was extremely useful, as
your example shows. The only alternative I know of is to write a
widget version for your processing.
