Apart from command line arguments and environment variables you cannot communicate with the process using child_process.exec. However you can use child_process.spawn to create a more integrated processes.

Enable key repeat in Apple Lion for Sublime Text in Vim mode
# Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key
# that enables you to choose a character from a menu of options. If you are on Lion
# try it by pressing and holding down 'e' in any app that uses the default NSTextField
# for input.
#
# It's a nice feature and continues the blending of Mac OS X and iOS features. However,
# it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode,
# as it means you cannot press and hold h/j/k/l to move through your file. You have
# to repeatedly press the keys to navigate.
