^b n/l - next/last window
^b ,   - rename window
^b  ?   - help
Windows Splitting
^b  %  - split window, adding a vertical pane to the right
^b " "  (space) - horizontal split is not bound to a key
^b ↑,↓, →, - switch to panel UP, DOWN, LEFT, RIGHT

3) bash
CSH is default shell under FreeBSD.
a) Install BASH statictly (installed in /bin, or to be more exact in mount point / ).
# make -C /usr/ports/shells/bash -D WITH_STATIC_BASH -DWITHOUT_NLS PREFIX=/ config-recursive install clean
# /usr/ports/shells/bash-static
# make install clean
b) Change shell
# chsh -s /bin/bash jfoo       # Change shell for user jfoo
# chsh -s /bin/bash            # Change shell for user root
c) Install cutomized aliases
Bash config file is located in ~/.bash_profile (is executed for login shells)

Bash Info:
# Run tasks in the background
#  bash lets you runone or more tasks in the background,
#  and selectively suspend or resume any of the current tasks (or "jobs").
# To run a task in the background, addan ampersand (&) to the end of its command line. Here's an example:
#     bash> tail -f /var/log/messages &
#     [1] 614

#  Each task back-grounded in this manner in assigned a job ID, which is printed to theconsole.
#  A task can be brought back to the foreground with the command fgjob number,
#  where jobnumber is the job IDof the task you wish to bring to the foreground.
#  Here's an example:   bash> fg 1

#  Alist of active jobs can be obtained at any time by typing
#  $jobs

# Moving the cursor:
#   Ctrl + a   Go to the beginning of the line (Home)
#   Ctrl + e   Go to the End of the line (End)
#   Ctrl + p   Previous command (Up arrow)
#   Ctrl + n   Next command (Down arrow)
#   Alt + b    Back one word
#   Alt + f    Forward one word
#   TAB        Tab completion for file/directory names

#  Ctrl + W   Cut the Word before the cursor to the clipboard.
#  Ctrl + K   Cut the Line after the cursor to the clipboard.
#  Ctrl + T   Swap the last two characters before the cursor.
#  Esc  + T   Swap the last two words before the cursor.
#  ctrl + y   Paste the last thing to be cut (yank)
