GNU Screen tips – Managing regions

Although I use tmux primarily for my “multiplexing needs” I hop into screen from time to time as well. Below are few tips for managing regions inside of GNU screen.

Your basic screen window probably looks somewhat like:

Ignoring hardstatus settings you basically have one session and one window inside of that session.

To split that window in half by vertical axis you can use following combination:

Ctrl+a |

You should now get something like:

To switch to that other vertical region you can use:

Ctrl+a [TAB]

After that your cursor should switch to that other window. You’ll notice that no window is selected there and there’s no shell to use in that window:

Basically you just created new region in which you can now place your existing window by simply switching to it with some of the following:

  • Switch to the window 1 (if you have it created already)
    Ctrl+a 1
  • Create new window and switch to it:
    Ctrl+a c
  • Switch to the next available window:
    Ctrl+a n
  • Switch to the previous available window:
    Ctrl+a p

You should after that have your window displayed inside of that new region and it should look somewhat like:

To kill the currently used region use:

Ctrl+a X

(note the capital X, combination of shift+x)

To kill all other regions except the one currently active (under cursor) use:

Ctrl+a Q

(also note capital Q, combination of shift+q).

You can also create vertical regions with following combination of keys:

Ctrl+a S

(note the capital S, combination of shift+s).
