Questions tagged [selection]

The selection can refer to text that has been highlighted, or it can refer to a choice made in UI elements that require one, e.g. a particular option in an HTML `select`. Selection is also the stage of a genetic algorithm in which individual genomes are chosen from a population for later breeding.

The selection can refer to:

  • a range of text that has been highlighted, a feature intended to mark the text for copying and, in editable areas, pasting over.

  • a choice made in UI elements that require one, e.g. a particular option in an HTML select. In UI elements, the selection is often made by means of drop-down boxes, radio buttons, checkboxes, file choosers, and more. Selections can be made with the mouse by clicking and dragging over the desired text, or by holding down the Shift key while navigating the text with the arrow keys. Selections are not usually permanent marks, and can often be removed just by clicking or selecting elsewhere.

  • the stage in genetic algorithms / programming is in which individual genomes are chosen from a population for later breeding (recombination or crossover).
