# I use pushd and popd to maintain a directory stack and so I like being able to navigate 
# around the stack with the cursor keys.  Here's how:
# 1) pushd <new dir>
# 2) use CTRL+UP, CTRL+LEFT or CTRL+RIGHT as follows:

# bind ctrl + cursor keys:
# left = prev; right = next; up = list
bind '"\e[1;5A":"dirs\C-m"'
bind '"\e[1;5D":"pushd -0 2>/dev/null\C-m"'
