# SCRATCHPAD
#
# An i3-like scratchpad using xdotool.
#
# Example:
#   ~$ scratchpad htop-pad urxvt -T htop-pad -e htop
#
# Explanation:
#   * If there is no window with title "htop-pad", a new
#   urxvt terminal will be run with "htop-pad" as title and
#   executing an htop instance.
#
#   * If the window already exists (visible or not), its
#   visibility will be toggled.
#
