??? When a link is clicked with the middle mouse button, most X-based browsers
will open the link target in a new window or tab instead of replacing the current
page; this can be configured in the browser??™s preference settings.
If you have a scrollwheel, your middle mouse button is probably connected to it;
pressing the scrollwheel will click the middle mouse button. If you??™re using a twobutton
mouse, you can configure it so that simultaneously pressing the left and right
mouse buttons results in a middle mouse click (Section 3.8).
5.5 Using the Clipboard
Most modern GUIs, both X-based and non-X-based, have a clipboard mechanism,
allowing you to copy or cut data from one document and paste it into another.
Table 5-1 outlines the standard clipboard operations.
Cut, copy, and paste operations may also be invoked from most programs??™ edit or
context menus.
Because X is networked-based, the program placing data onto the clipboard and the
program receiving the data from the clipboard may not be on the same computer??”
in fact, they may not be in the country. They may also have different capabilities as
far as the types of data which they understand.
