I'm new to linux so i need help,the other day i was watching movie on VLC,while fast forwarding it froze completly,as it was in full screen mode i could not do any thing about it,thankfully it returned to normal after 20-30 seconds...
On windows i could have used a task manager to kill the frozen app by using ctrl+shift + esc or ctrl+alt+del....
is there any similar taskmanager or shortcut is to kill the frozen apps like nautilus or VLC??
thank you....
PS: i think 'system monitor' can be used to kill an frozen app,but is there a keyboard  shortcut to open system monitor??
