Recently I installed Ubuntu and I've some troubles with typing text on terminal, the problems not occurs on the text editors. I can't select the text to right or left using shift+arrow. When I try it, like shift+left, D letter is typed on the line, and C is typed using shortcut with arrow right. Resuming, I've two issues:
shift+arrow not working;shift+home or shift+endI installed KDE on Ubuntu. Please, anyone can help me?
The standard Terminal does not use the same shortcuts (or even the same cursor behavior) as you might expect in a browser or text editor window. The shift key by itself does not select text that way. shift+home will scroll to the top, shift+end to the bottom, and using it with pg up/pg down will scroll up/down one screen. The arrow keys are mapped to A/B/C/D.
As you can see on this list, most of the commands are for moving around and managing processes. I usually just select text with the mouse, then copy with ctrl+shift+c and paste with ctrl+shift+v. As discussed on Ask Ubuntu, there appears to be no easy way to select arbitrary text without the mouse.
Alternative terminal programs may offer more options.
Update While this is not a standard shortcut, you can go into Terminal's Edit > Preferences > Shortcuts, find the Edit section, click the Select All row in the Shortcut Key column, then enter a new shortcut like ctrl+shift+a. This new shortcut will then let you then copy all of the terminal text.
