15.7 X Cut and Paste
====================
If you are using Emacs with the X window system, there is an easier way
to move small amounts of data into and out of the calculator: Use the
mouse-oriented cut and paste facilities of X.
The default bindings for a three-button mouse cause the left button
to move the Emacs cursor to the given place, the right button to select
the text between the cursor and the clicked location, and the middle
button to yank the selection into the buffer at the clicked location.
So, if you have a Calc window and an editing window on your Emacs
screen, you can use left-click/right-click to select a number, vector,
or formula from one window, then middle-click to paste that value into
the other window. When you paste text into the Calc window, Calc
interprets it as an algebraic entry. It doesn’t matter where you click
in the Calc window; the new value is always pushed onto the top of the
stack.
The ‘xterm’ program that is typically used for general-purpose shell
windows in X interprets the mouse buttons in the same way. So you can
use the mouse to move data between Calc and any other Unix program. One
nice feature of ‘xterm’ is that a double left-click selects one word,
and a triple left-click selects a whole line. So you can usually
transfer a single number into Calc just by double-clicking on it in the
shell, then middle-clicking in the Calc window.
