How to select every atom or object of the same kind

Select one atom, bond or object, press Ctrl+K and choose Select same. Every atom of that element, every bond of that type, or every object of that kind and color is selected.

On a Mac, Ctrl is Cmd.

Steps

  1. Select one example: an atom, a bond, an arrow, a shape or a text block. With the keyboard, move to an atom with Alt+. and press Enter.

  2. Press Ctrl+K, type Select same, and press Enter.

  3. Everything like it is selected, and the status line says how many, for example "Selected 4 atoms".

An atom Every atom of the same element
One bond Every bond of the same type

Selecting a chlorine and an arrow together selects every chlorine and every arrow like that one.
