unexpected behaviour of Ctrl-a x and Ctrl-a X in screen?! regions, locking

Question

According to the screen manual (version 4.0.2.)

C-a x
C-a C-x     (lockscreen)  Lock this terminal.
C-a X       (remove)      Kill the current region.

But what actually happens when I use it (Screen version 4.00.03 (FAU) 23-Oct-06):

C-a X   locks the terminal and asks me for the password. When I enter the correct passwword, I am back in screen but the region is killed (wtf)
C-a x   does nothing apparently

Please note the differences between x (lowercase) and X (uppercase).

Why is there a mixup between the functionalities of C-a X and C-a x? How can I fix this?

I am on CentOS release 5 (Final).

Solution

Perhaps your screenrc (personal or system wide) has changed these bindings from the defaults.

To see what they're currently set to, view the bindings by hitting the "help" combo -- C-a?.

See if the entries for lockscreen and remove match what the man page says.

"> But I'm assuming that the 'Kill the current region' does nothing because you only use one region." But I did create a new region before doing Ctrl-a X!

@gojira: sry, no need to be shouting. You didn't say it, and it is not uncommon for users of screen to confuse windows and regions

I am not shouting, I just clarified that I already had a region open which I thought was implied, but probably I was not clear enough. So yes, the region is open it's just that the functionalities of C-a X and C-a x are mixed up. Would be happy if someone knows the reason or a solution. Thanks.
