I don't know how special they are. Escape sequences for responding to mouse events and checking mouse pointer status have been around for 15 to 20 years or more that I know of. We used them in VMACS in some of the earliest terminal emulators for Macintosh and they are a standard feature bult into all terminal emulators derived from XTerm. >Think about it this >way: when you manipulate the mouse, events there will be >corresponding MOUSE events in the Windows (say) event loop, but >either you'd have to fire KEY events (to which a terminal would >respond), or do something with the corresponding events at the X11 >level (assuming you are using it).

Mouse events come across as ESCAPE sequences, like function keys indicating mouseup or mouse-down and row and column position, and there are ESCAPE sequences going back the other way to turn on mouse reporting and to request a status update. We used them extensively for menu navigation and text editing, including a logical multiple line highlight and cut/copy/paste. --------------------------------------- Jim Self Systems Architect, Lead Developer VMTH Computer Services, UC Davis (http://www.vmth.ucdavis.edu/us/jaself) ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
