I'd like to write a function that delays the evaluation of a function (say) $5$ seconds after I hit Shift+Return. Is this possible?

Use the Pause function:

SetAttributes[delayedFunction, {HoldFirst}];
delayedFunction[function_] := (Pause[5]; function);
  • $\begingroup$ More useful if defined as delayedFunction[function_, dt_] := (Pause[dt]; function) $\endgroup$

An alternative is to use the built in function, RunScheduledTask

RunScheduledTask[z = 7, {5}]
