# 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. |
