The IDE has its own clipboard, which is independent of the operating system’s clipboard. The Cut, copy and paste commands operate with this internal clipboard. Selected text in the Clipboard window (accessible via ”Edit—Clipboard”) can be pasted into other parts of the IDE that accept text input.
To access the OS clipboard, use commands from the menu ”Edit—Copy from Windows” and ”Edit—Paste to Windows”. If interaction with the OS clipboard is not supported, these menu options will not be visible.
The default shortcut keys for cut, copy and paste are Shift-Del, Ctrl-Ins and Shift-Ins, respectively. On linux, the Ctrl-Ins and Shift-Ins may not be available to the IDE without special terminal configuration (see appendix G.3).
It is possible to activate shortcut keys Ctrl-X, Ctrl-C and Ctrl-V for cut, copy and paste commands (section 6.12.4, page 376). In this case, the default functionality of these shortcuts will be overridden.
