The HP Prime calculator keeps a list of all the variables you create. You can see this list by pressing
a
, tapping ,
and selecting User Variables . A list of user-defined variables appears. To use a listed variable in a current calculation, select
it from the list. To delete a listed variable, use the cursor keys to highlight it and then press

Copy and paste
Copy-and-paste functionality is available. The copy options vary depending on where you are in the calculator. For example,
if you are creating a matrix in the Matrix Editor, choosing copy (
SV
) simply copies the value of the highlighted cell to the
clipboard. You navigate to the target cell, press
SM
to display the clipboard, and choose the entry you want to paste.
If you are working in the Program Editor or Note Editor, pressing
SV
gives a
number of copy options. The illustration at the right shows the menu items you see
when you are in the Program Editor: mark where to begin a selection, mark where to
end the selection, select the current line, select everything, cut what is selected, and
copy what is selected.
In the Spreadsheet app, the paste functionality gives you a choice of what to paste: the copied value, the underlying formula,
the format of what was copied, or the formula and its associated formatting.
In the List Editor, you can select part of a list, an entire list, or a rectangular array of elements from multiple lists. This
selection can then be copied and pasted in either the Matrix Editor or the Numeric view of the Spreadsheet, Statistics 1Var,
or Statistics 2Var apps. Similarly, in the Matrix Editor, you can select one or more rows, one or more columns, a sub-matrix,
or the entire matrix. This selection can then be copied and pasted in either the List Editor or the Numeric view of the three
previously listed apps.
Generally, the copy-and-paste function allows you to transfer numbers and expressions throughout the calculator software.
