#X text 98 411 Also note that key combinations \, such as SHIFT+7 produce
a different result than SHIFT or 7 alone.;
#X text 168 346 Some keys \, such as SHIFT or the F1-F12 series all
produce a zero \, but we can see by the [bng] that the event is not
ignored completely...but the numeric "ID" of the key is not captured
successfully. (This may produce different results on different systems.)
;
#X text 168 293 - the number received at the outlet represents the
numeric "ID" of a key on the computer's keyboard. This event occurs
when the key is pressed down. Only one event is captured at a time.

;
#X text 100 95 [key] reports the (system dependent) numbers of "printing"
keys of the keyboard.;
#X text 99 477 Caveat - this only works if Pd actually gets the key
events which can depend on the stacking order of windows and/or the
pointer location. This is dependent on the system.;

#X text 19 37 Most \, if not all \, programming environments provide
us with tools to capture 'user initiated' events from the operating
system. Keyboard input \, mouse clicks \, and mouse movements are the
most common events in this 'user event' category.;
#X text 19 103 Pd's [key] \, [keyup] \, and [keyname] are complimented
by the externals such as [gemmouse] and [nimouse] to provide us with
a full range of tools to gleen a user's activities at the computer.

#X text 20 290 hmmm...wouldn't it be great if Pd also gave us onChange
\, onBlur \, onFocus \, onClick \, onDblClick \, onDragDrop \, onLoad
\, onMouseDown \, onMouseOver \, onMouseOut \, onMouseMove \, onUnload...?
