October 23, 2016	Random texts are selectable at ZART and at Telegram practice.
October 01, 2016	AF frequency changing was corrected. Telegram option was added to textgroup.
June 22, 2016	Play function was added to straightKey object. The jsMorse plays the selected text from now on. ZART lessons are available in a textarea. You can practice RX and TX with words of ZART or with other typed or pasted text in the textarea.
May 16, 2016	Touchstart and touchend events was added to Eventlistener. The jsMorse runs also on mobile devices from now on. Practice text selection was optimized.
April 25, 2016	Signaldigit correction uses 1 digit margin at long mark or gap. The character recognition was optimized at mouse or keyboard events. Above that, a timer decodes the remaining digits after 5 units time.
January 17, 2016	The jsMorse test version is available on the WEB.
Idea	Browser based Morse code key emulation and analysis. The program detects signal from mouse or keyboard, and a few JavaScript eventhandler calculate the signal time, start or stop the AF oscillator, draw the signal time-line and encode the letters. Therefore you can online learn and practice the Morse encoding anywhere and anytime... [Autumn 2015]
