Instant-starting a program

Hi, I'm new to this mod and i have a problem.
How can you make your computer instant start a program when you right click it.
Is it over events or somting? I dont understand events that much.

Also, is there someway to "tick" bundled cable? Like in Eloraam computer TICKS.

Right off the bat, edit startup, shell.run(PROGRAMTORUNATSTARTUP)
TICKS? sleep(TIME) TIME being time in seconds to delay.

Allright, thanks man helped a lot :)/>/>

Or just have a file called 'startup' with the code inside

By the way, just measuring times can lead to strange results. More advanced tick detection methods are needed to work smoothly.
