If a process becomes unresponsive in WINDOWS then we press “alt+ctrl+del” to invoke the task manager & then terminate the process.Is there any similar way to invoke the Linux Terminal so that we can end a process by the ‘kill’ command when it becomes unresponsive?Any help would be gladly accepted.

Umm, I’ve seen plenty of documentation on all the commands in Linux, but I haven’t seen how to perform the most simplest thing like moving up and down through the terminal to view what commands you’ve done and what help files you’ve displayed. Just the keyboard replacement for using the scrollwheel would be great. Thanks.
