シフトキー
The keyboard symbol for the Shift key (which is called Level 2 Select key in the international standard series ISO/IEC 9995) is given in ISO/IEC 9995-7 as symbol 1, and in ISO 7000 "“Graphical symbols for use on equipment”" as a directional variant of the symbol ISO-7000-251. In Unicode 6.1, the character approximating this symbol best is U+21E7 (⇧). This symbol is commonly used to denote the Shift key on modern keyboards (especially on non-US layouts and on the Apple Keyboard), sometimes in combination with the word “shift” or its translation in the local language. This symbol also is used in texts to denote the shift key.
