Choose a function in the lower part of the Elements pane. These functions are also listed in the context menu of the Commands window. Any functions not contained in the Elements pane need to be typed manually in the Commands window.
The following is a list of all functions that appear in the Elements pane. The icon next to the function indicates that it can be accessed through the Elements pane (menu View - Elements) or through the context menu of the Commands window.
List of functions

Deiling
Inserts the factorial sign with one placeholder. You can directly type fact <?> in the Commands window.
You can also assign an index or an exponent to a function. For example, typing sin^2x results in a function "sine to the power of 2x".
When typing functions manually in the Commands window, note that spaces are required for some functions (for example, abs 5=5 ; abs -3=3).
