Blinking Cell when select

[Joeun]

Hi guys
I wanted to create a blinking cell when cell is select

Condition 1
Example:
select A3 = K17 blinking
select A8 = R11, R13, R15, R17, R19, R21 blinking (multiple cell blinking together)
select A13 = I9, I11, I13 blinking (multiple cell blinking together)
and apply for the rest column A
blinking will be continuous until cell A3:A18 is not select

Condition 2
Example: Inverse of condition 1
select M5 or M7 or M9 or M11 or M13 or M15 or M17 or M19 = A9 blinking
select K15 or K19 = A14 blinking


Thanks in advance.

What type of blinking do you want? and how many seconds?
For example: font (black - white - black, within 1 s) or background (current color - white - current color, 2s)
???

background (current color - white - current color, 1s)
