Put your ROS_MASTER_URI into a terminal title, edit .bashrc:

# If this is an xterm set the title to user@host:dir
case "$TERM" in
xterm*|rxvt*)
    PS1="\[\e]0;\$ROS_MASTER_URI ${debian_chroot:+($debian_chroot)}\u@\h: \w\a\] $PS1"
    ;;
*)
    ;;
esac

Though at a glance it may appear to be the hostname of the computer the terminal is running on.

Re-assign keys

Swap pgup/pgdn and home/end on laptops.

sudo vi /usr/share/X11/xkb/symbols/pc

    key <HOME> {        [  Prior                ]       };
    key <PGUP> {        [  Home                 ]       };
    key <DELE> {        [  Delete                 ]       };
    key  <END> {        [  Next               ]       };
    key <PGDN> {        [  End                  ]       };

Then logout and log back in.
