I use screen everyday, yet i must admit i’ve always been only scratching its surface. Today, coworker +kelvin showed me how to kill a screen window with CTRL-a + k.

How did i do it in the past ?? Err, this is embarrassing, i usually either just type exit in the window.

Finally, let’s say if u start with windows 1$, 2$, 3$ & 4$. When u kill 3$, 4$ still retains its “4”. To fix this issue, you can CTRL-a :number 3 to reset “4” to “3”.

PS: a personal todo is to dig into man screen .. or bug someone to do the digging & teach me :)
