We've all heard it...there's frustratingly no working ALT code for a capital Delta on Windows. Every other Greek letter works, except for the one you and I would type consistently on this forum. We have to Google it, and copy and paste it from some website every time. But that's not true! You can make the delta symbol work with the Alt key!
I found it here: https://www.reddit.com/r/windows/comments/18joaq/how_do_you_get_the_delta_symbol_on_a_windows/
Go to the Command Prompt, and enter this sequence:
reg add "HKEY_CURRENT_USER\Control Panel\Input Method" /v EnableHexNumpad /t REG_SZ /d 1
Then, log off and log back on.
Open a text editor. It can even be this forum.
Hold [ALT] and [NUMPAD +] and type '0394' on the keypad.
