Palettes provide an unprecedentedly simple way to access the full range of Mathematica's capabilities.
To see how a palette works, choose Generate Notebook from Palette, then choose Show Expression, and look at the Mathematica definitions the palette contains.
A palette of mathematical and other notation understood as input by Mathematica (opened by default when Mathematica starts).
Some basic Mathematica calculations (available from the Palettes menu).
Functions for in-place manipulation of parts of algebraic expressions (available from the Palettes menu).
A palette of common colors to use in Mathematica (the defaults allocated by Mathematica on low-color displays).
An interactive tool for creating remarkable polyhedral shapes.
A periodic table in which pressing an element pastes a description of its properties.
Notation and values of common physical constants.
A palette for creating new notebooks with different style sheets (available from the Palettes menu).
Moving around the selection in a notebook.
A tool for creating demos that can be run either within Mathematica or over the web.
Common objects and operations needed in mathematical typesetting (available from the Palettes menu).
The complete collection of special characters available by default in Mathematica (available from the Palettes menu).
Common European characters (available from the Palettes menu).
