How to close unresponsive activities

NOTE: The content of this page is considered DEPRECATED and OBSOLETE It is preserved for historical research, along with its talk page. Page not linked from anywhere in the wiki Turtle Art is particularly prone to seizure... but it's not the only activity where you need a bigger hammer to close it... Really need one hot key combo that will kill an application without using the GUI! Please! Here's a screencast of how to get to the terminal and try to shut stuff down. I'm running Sugar in emulation mode so YMMV.
