Arduino Uno [Keyboard] Marco keys

HI,

After looking this link and reading how some functions works and looking some tutorials
https://www.arduino.cc/en/Reference/MouseKeyboard
I wanted to give a try to make some macro keys (buttons), had the idea like opening (browsers, programs) just with a click of a button, so i wrote a simple code of trying to open something and suddenly while compiling the code I got this message :
"keyboard" only supported on the Arduino Leonardo

well reading few topics and comments about that people saying that it's not possible with arduino Uno to send "key" signals thru usb (?!)

Looking in the other way the arduino Uno can read keyboard keys and which that keys can be send to processing to do some actions.

So the main point of this topic is: How can I make the arduino Uno send keyboard keys and do some actions?

And a interesting question: If the Uno is not capable to send commands then what's missing from the board?

Here we go, that's all what i needed, a bit of extra work but nvm :smiley:

Good luck, myself! :smiley:
