I was reading an answer about placing a tabs bar at the bottom of GNU Screen, and it said to press Ctrl+a+A. Clearly I cannot press A again while still pressing a, and why are the two capitalized differently?I have tried pressing Ctrl+A, Releasing, and than pressing A, which does nothing, and Pressing Ctrl+A, releasing A, and then Pressing it down again. Nothing of the sort works. The answer is at: How do I use tabs with the Linux "Screen" program?.

  • looks like a failure in the documentation to properly inform the users on the proper keypresses.

You can't press ctrl+a+A.

The answer you are referring to contains incorrectly formatted key bindings. To rename a window in GNU Screen press ctrl+a, release both keys and then press shift+a. Conventional format to present this key binding is ctrl+a A.


According to this page you need to press ctrl+a to send commands to the outer screen, and then press a letter for specific keys.

So you press ctrl+a then release both, then press shift+a to send this ctrl+a A

  • @Chipperyman Thanks, I actually knew about doing this, but I was doing too many things at the same time and completely forgot. Thanks for adding though.

You were on the right track... but be aware, that the command are case-sensitive.

So, to rename a GNU screen window do the following:

Press CTRL and a together. Release them. Then press SHIFT and a together. That makes a capital A.
