Shift key

When the Caps Lock key is engaged, the Shift key may be used to type lowercase letters on many operating systems, though not on macOS or on Microsoft Windows keyboard layouts that have the SGCAPS feature.

In Unicode 6.1, the character approximating this symbol best is U+21E7 upwards white arrow (⇧).

[3] 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 phenomenon is known as "masking" and is a fundamental limitation of the way the keyboard electronics are designed.
