The comments in the example _inputrc provided by Bash explain the mapping:
# Translation characters for extended keys
# w/o SHIFT, CTRL, or ALT = "\e["
# w/ SHIFT                = "\e[1"
# w/ CTRL                 = "\e[2"
# w/ ALT                  = "\e[3"

# then add for the key:
# "A" = Up Arrow
# "B" = Down Arrow
# "C" = Right Arrow
# "D" = Left Arrow
# "E" = Insert
# "F" = Delete
# "G" = Home
# "H" = End
# "I" = Page Up
# "J" = Page Down
# "XA" = F1, "XB" = F2, "XC" = F3, "XD" = F4,  "XE" = F5,  "XF" = F6
# "XG" = F7, "XH" = F8, "XI" = F9, "XJ" = F10, "XK" = F11, "XL" = F12
#

So the "up arrow" is encoded as:
\e[A
Shifted "up arrow":
\e[1A
Ctrl "up arrow":
\e[2A

etc.
