By default, a CAS function is presented on a CAS menu using its descriptive name, not its command name. Thus the
command name gbasis is presented as Groebner Basis and proot is presented as Find Roots. If you prefer
the CAS menus to show the command names instead, deselect the Menu Display option on page 2 of the Home Settings
screen (see "Home Settings" on page 12).

### Using CAS in Home view

To use a CAS function in Home view, select the function from the CAS menu while you are entering your expression. The
CAS. prefix is added to your CAS function to remind you that this component of your expression will be evaluated by the
CAS. You can also copy an item from CAS history to an expression you are entering in Home view. Press M and select Get
from CAS. The CAS view opens. Tap the item you want, and it is copied directly to the cursor position in Home view. Likewise,
you can insert an item from Home view history into an expression you are entering in CAS view. Just press M and select
Get from Home. Home view opens. Tap the item you want and it is copied directly to the cursor position in CAS view.
