Tap your keyboard's keys to generate morse code. You can input using zxcvbnm,. and space. The text will split onto two separate lines and various durations (such as how long a dash must be) can be adjusted manually. As the UI is just a .png image, you can switch it out with any custom image with the exact same name.
+ / - Adjust press duration for a dash
UP / DOWN Adjust character accept delay
RIGHT / LEFT Adjust how long until a word separator is inserted
Backspace Clear current text
Enter Toggle automatic word separation off / on
ESC Quit
I wrote this program, because I couldn't find a very good morse practice tool that would allow me to write freely. I used this tool to learn the alphabet.
