Many GUI applications (but not all) also support the Mac/MS-Windows-style "copy-paste": Select the text. Use the menu item "edit"-"copy" (either from the pull-down menu, or a local menu activated with the <RightMouseButton>). Switch to the location where to copy to. Use the menu item "edit"-"paste". This works fine for applications which use the same toolkit (e.g. KDE or GNOME) but does not always work across toolkits (e.g., from a GNOME application to the KDE application).
As a keyboard shortcut for the last method, I can use <Ctrl><c> for copying the highlighted text and <Ctrl><v> for pasting. Text can be highlighted without mouse using <Ctrl><Shift><RightArrow>.
but seems i'm still having GDM problems
that make my X Server cant started yet
now still using Command Line Interface (CLI)
and so the mouse cant be used.
and there's no way to copy n paste is it ?
