What is Shift1?
1.
This is sometimes used to replace the common exclamation point, but most often they are used together.
It usually expresses extreme happiness or anger about something, and a regular exclamation point isn't enough to express how the person feels.
Occasionally the word shift is left out and just the number 1 is used.
