caretBlinkRate
How fast the component's caret blinks: the delay in milliseconds between the caret being shown and being hidden again. 0 holds it steady.
The rate belongs to the component, not to one caret. A caret that arrives later - one a caret declared anywhere in the modifier chain installs - is given the declared rate as it is installed. Removing the declaration puts the rate read at attach onto the caret the component carries then, and a caret the modifier let go of keeps the declared rate.
Return
this modifier with the blink rate declared on it.
Parameters
rate
the delay in milliseconds between blinks, or 0 for a caret that does not blink.
