Hitchhiker's Guide to Openbsd

7.8 - EVERYTHING I TYPE AT THE LOGIN PROMPT IS IN CAPS!
This is a feature, not a bug, actually. 
Virtually all Unix commands and user names are entered using all lowercase. However, some very old 
terminals were only capable of uppercase characters, making them difficult, if not impossible, to use 
with Unix. As a workaround, if you entered your user name in all uppercase, 
getty(8)
 would assume 
your terminal was "lowercase challenged", and simply interpret everything you type as lowercase, while 
echoing it as uppercase. If you have a mixed-case or uppercase password, this will make login 
impossible. 
Hitting CTRL-D at the login prompt will cause getty(8) to terminate, and 
init(8)
 will relaunch a new 
one, which will accept uppercase and lowercase properly. 
7.9 - What is tmux?

7 - Keyboard and Display Controls
For those familiar with the "screen" program, provided as a package, or window(1) which used to be in 
base, it may be easiest to answer this by saying that 
tmux(1)
performs many of the functions as screen 
and window, with many additional features. 
For those not familiar with these programs, tmux is a terminal multiplexer. This is a program which 
allows a number of other processes to share the same screen for input and output. In tmux, such a 
collection of programs is known as a session, with each program contained in a tmux window. 
In addition to sharing the terminal, tmux lets you detach a session and its windows from the screen, 
leave them continue running in the background, and later reattach them to the same or to a different 
screen. A session may be detached manually or through an unexpected event such as network 
disconnection, in either case the programs survive and continue running as normal. 
tmux also has many other features such as splitting a single window into multiple sections (known as 
panes), a history of text printed in each window, copying and pasting text between windows, 
configurable key bindings, and terminal locking. Take a look at the 
tmux(1)
man page for further 
information.
