How do I enable every x seconds.

Hello everyone,I'm having problems getting to grips with the concept of disable and enable,on the every x seconds event.

"On start of layout I don't want every x seconds to be enabled until I click a keyboard key"

System>every 1.0 second> add 1 to timer.

Some advice would be great.

Use a global variable as a condition.

On key pressed, set variable to 1 (is 0 by default)

Every x seconds, if variable=1, add to timer

Thank you
