Help with Engineer blink/blink mod macro

I’m a complete macro nub, but is it possible to macro blink and the engineer blink Electro-Jump? So that I blink when i have press blink, but when I press shift+same key i use the engineer blink?

#showtooltip
/use [mod:shift] Electro-Jump; Blink

thanks but it didnt work, Electro jump is on the the belt as an on use item.

its not a spell I have.

like this

#showtooltip
/use [mod:shift] 6; Blink

6 is the belt slot
