Key Press Function Summary
How long a key is depressed, and the combination of the keys pressed is
important. The term (Momentarily) describes a key press of typically less
than 1 second. Whereas (Press & Hold) is used to imply a key press of
typically longer than 1.5 seconds.
For example: When using a PC keyboard to type a CAPITAL letter you would
“press and hold” the SHIFT key and “momentarily” depress the LETTER key.
In addition, a key(s) “function” is executed on the key RELEASE, not the key
DEPRESS of that key(s). This is important since some keys execute
different functions based on how long they are depressed. These key
operations, once tried, quickly become intuitive.
