keyboard.print vs. keyboard.write vs.

I was reading up on keystrokes here:

I'm still not entirely sure what the differences are between those three functions. Could somebody please explain the differences to me a bit better? I'm writing a program that involves sending keystrokes to my computer, and I'm not quite sure which one is the appropriate one to use. Thanks.

The should be followed by a Keyboard.release(). That is how your 'real' keyboard is. You could keep the button pressed a long time. For example, if you want to move forward in a game, you want to keep pressing that button.

To make it simpler for you, the Keyboard.write() sends a single character. Like you press a button on the keyboard and release it.

To send a string of text, the Keyboard.print() function is used. Like typing a whole sentence.

To send a string of text followed by Enter, the function Keyboard.println() is used.

Why so many functions ? Well, the 'normal' basic functions are the and the Keyboard.release(). The other functions are a result of the 'stream' class. The 'stream' class is a common class used by other classes, it uses the same functions for all sorts of communication (write,print,println).

A write (or print) is basically a press + release.

So to send "normal" text, writing or printing is fine. eg.

Keyboard.print ("hi there");

However if you want to press a key (eg. Shift) and then press another key (eg. Enter) then you would probably do 2 x press and then a releaseAll.

This is the code for write:

size_t Keyboard_::write(uint8_t c)
    uint8_t p = press(c);       // Keydown
    uint8_t r = release(c);     // Keyup
    return (p);                 // just return the result of press() since release() almost always returns 1

So you can see it just presses and releases the required key.

Thanks so much for your help, guys!
