I've been experimenting around trying to develop a desk accessory that
can be activated by a 'hot key'... In order to do this I thought I
could have evnt_multi() wait for keyboard messages and then when the
right key was pressed, the accessory could activate itself.
Unfortunately it appears that as a DA the program does not get notified by
evnt_multi when a keyboard event occurs... When linked and run as a
regular program it receives the messages properly. Has anyone seen this
before? Is there a work around? The DA reacts to timer and message events
properly it just doesn't seem to get anything from the keyboard.

This is normal - and is a feature - just like the workstation on your desk, applications only receive keyboard input when their window is on top. (On the atari, "on top" is coupled to input focus.) You will get keyboard input only when a window you created from the accessory is the top window on the desktop. To implement "hot key", you will have to do something more intrusive. Several possibilities come to mind: 1. Using the timer feature of event_multi, poll the SHIFT and ALT keys for a specific combination. You can check the shift key state with one of the bios/xbios routines. (don't use the other event wait routines from .ACC's, only event_multi is known to work correctly.) 2. Steal the keyboard interrput vector and set a flag when you see the keystroke you want. Pick up the flag when the timer expires. | |||||
