Press the Windows key using "keyboard.press();" Is it possible to allow an Arduino Leonardo to simulate pressing the Windows key using the keyboard.press(......); command?

If so, what is the required value?
They Keyboard.press() command accept modifiers per the documentation. You may need to do multiple press() commands before releasing.

For example, if you want to launch File Explorer you could use:

Keyboard.press(KEY_LEFT_GUI);
Keyboard.press('e');
Keyboard.releaseAll();


This is equivalent to shortcut keys Win + E.

The modifier GUI is what stands in for the "command key" which is the Windows Logo on a PC or clover (⌘) on a Mac.

I don't have any restriction on the higher value on my board (Pro Micro), as indicated by @frarugi87.
