Click the down-pointing arrow at the right of this box to display other groups; click on the appropriate group to select it. When the cursor is passed over a special-character link, the link is underlined; clicking on the underlined link enters that character at the current cursor position in the edit window. Figure 2.
The Arrows block contains eight emoji: U+2194–U+2199 and U+21A9–U+21AA. [3] [4]The block has sixteen standardized variants defined to specify emoji-style (U+FE0F VS16) or text presentation (U+FE0E VS15) for the eight emoji, all of which default to a text presentation.

Often a control character can be typed on a keyboard by holding down the Ctrl and typing the character shown after the caret. The notation is often used to describe keyboard shortcuts even though the control character is not actually used (as in "type ^X to cut the text").
The use of the caret for exponentiation can be traced back to ALGOL 60, [citation needed] which expressed the exponentiation operator as an upward-pointing arrow, intended to evoke the superscript notation common in mathematics. The upward-pointing arrow is now used to signify hyperoperations in Knuth's up-arrow notation.
↑, a notation of Knuth's up-arrow notation for very large integers; ↑, a mathematical game theory position Up; ↑ or Sheffer stroke, the logical connective "not both" or NAND; ↑, the APL function 'take' "Increased" (and similar meanings), in medical notation; ↑, a chemical symbol for production of gas, which bubbles up.
Upward arrows are often used to indicate an increase in a numerical value, and downward arrows indicate a decrease. In mathematical logic, a right-facing arrow indicates material conditional, and a left-right (bidirectional) arrow indicates if and only if, an upwards arrow indicates the NAND operator (negation of conjunction), an downwards arrow indicates the NOR operator (negation of ...
The main reason for this arrangement is that the arrow keys are not ergonomic to use with a right-handed mouse. During the early days of gaming, this was not a problem as the mouse was not used; the arrow keys controlled both movement ↑ ↓ as well as looking around ← →, with strafing done using modifier keys (usually Alt + ← →).
