In situations where a block was used, the block was usually created by inverting the pixels of the character using the boolean math exclusive or function. In text mode displays, it was not possible to show a vertical bar between characters to show where the new text would be inserted, so an underscore or block cursor was used instead. In most command-line interfaces or text editors, the text cursor, also known as a caret, is an underscore, a solid rectangle, or a vertical line, which may be flashing or steady, indicating where text will be placed when entered (the insertion point).

The cursor for the Windows Command Prompt (appearing as an underscore at the end of the line) He wrote that the "bug" would be "easier" and "more natural" to use, and unlike a stylus, it would stay still when let go, which meant it would be "much better for coordination with the keyboard." Īccording to Roger Bates, a young hardware designer at ARC under Bill English, the cursor on the screen was for some unknown reason also referred to as "CAT" at the time, which led to calling the new pointing device a "mouse" as well.

On 14 November 1963, while attending a conference on computer graphics in Reno, Nevada, Douglas Engelbart of Augmentation Research Center (ARC) first expressed his thoughts to pursue his objective of developing both hardware and software computer technology to "augment" human intelligence by pondering how to adapt the underlying principles of the planimeter to inputting X- and Y-coordinate data, and envisioned something like the cursor of a mouse he initially called a "bug", which, in a "3-point" form, could have a "drop point and 2 orthogonal wheels". The term was then transferred to computers through analogy. A cursor is a name given to the transparent slide engraved with a hairline used to mark a point on a slide rule. In human–computer interaction, a cursor is an indicator used to show the current position on a computer monitor or other display device that will respond to text input.Ĭursor is Latin for 'runner'.
Someone may type several carets in chat (e.g., ^^, ^^^, or ^^^^^^^) to tell others to read the above line or what someone said above is true.A blinking text cursor while typing the word " Wikipedia". The caret key is used in keyboard shortcuts like Ctrl+ Shift+ ^. In C-style programming languages, the caret is used for a bitwise XOR. Many programs that support regular expressions (regex) use ^ to match the first character in a line or string. For example, in Perl, a user may use the below regular expression to replace the first character in the variable "myvariable" with an uppercase character.
Using a caret in programming and regular expressionsĬarets can be used in computer programming languages for various reasons. In other words, press and hold the Control or Ctrl key and then press the letter following the caret to do the keyboard shortcut. as a notation or short way of saying Ctrl-X, Ctrl-C, Ctrl-Z, etc. What a caret is used for on a computer? Using a caret for shorthand for CtrlĬomputer documentation may list commands such as ^X, ^C, ^Z, etc.
To create a caret on a smartphone or tablet, open the keyboard, go into the numbers (123), then (#+=) or symbols (sym), and tap the ^ symbol. Creating the ^ symbol on a smartphone or tablet

Doing the Alt code Alt+94 can also create a caret.
