module Vedeu
module EscapeSequences
# Provides mouse related escape sequences.
#
# The X10 compatibility mode sends an escape sequence on button
# press encoding the location and the mouse button pressed. It is
# enabled by sending `\e[?9h` and disabled with `\e[?9l`.
#
# On button press, xterm(1) sends `\e[Mbxy` (6 characters).
# Here b is button-1, and x and y are the x and y coordinates of
# the mouse when the button was pressed. This is the same code the
# kernel also produces.
#
# Normal tracking mode (not implemented in Linux 2.0.24) sends an
# escape sequence on both button press and release. Modifier
# information is also sent. It is enabled by sending `\e[?1000h`
# and disabled with `\e[?1000l`. On button press or release,
# xterm(1) sends `\e[Mbxy`. The low two bits of b encode button
# information: 0=MB1 pressed, 1=MB2 pressed, 2=MB3 pressed,
# 3=release. The upper bits encode what modifiers were down when
# the button was pressed and are added together: 4=Shift, 8=Meta,
# 16=Control. Again x and y are the x and y coordinates of the
# mouse event. The upper left corner is (1,1).
#
# - From CONSOLE_CODES(4) (`man console_codes`)
