Control-X (or ⌘ Command + X) to cut. Control-C (or ⌘ Command + C) to copy. Control-V (or ⌘ Command + V) to paste. The IBM Common User Access (CUA) standard also uses combinations of the Insert, Del, Shift and Control keys. Early versions of Windows used the IBM standard.
A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the format &#nnnn; or &#xhhhh; where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form.
To use the shortcut, turn on NumLock / Fn, and make sure the cursor is flashing where you want the symbol to go. Press and hold the alt key, and then press numbers. You don’t need to press the ...
