How to stop cursor blinking in Pages
NSTextInsertionPointBlinkPeriod is outdated. As of 10.9, OS S now has separate variables for ON and OFF times. 1000 represents one second. The following 2 commands can be used:

defaults write -g NSTextInsertionPointBlinkPeriodOn -float 1000


and

defaults write -g NSTextInsertionPointBlinkPeriodOff -float 1000


These numbers will set the on blink to 1 second and the off blink to one second (default).
