Double tap vs single tap a key

[bacon]

I'd like to create a macro that does one thing if I single press a keyboard key and another if a double press. So if I map the macro to the insert key and press it once it sends the F1 key and if I tap the insert key twice with in a .4 millisecond time range it sends the F2. Any suggestions how to accomplish this? I've tried several different programs and haven't found one that works.

int+ g_InsertKeyTime; int isDouble=GetTickCount-g_InsertKeyTime<=400; g_InsertKeyTime=GetTickCount

if isDouble
,out "double"
else
,out "single"

Wow thanks for the quick response! The macro seems to output "single" AND "double" when double tapping Insert. Anyway to make it only output "double" on a double tap and "single" on a single tap?

It is more difficult. The single-tap macro would run with 0.4 s delay. If it is OK, I'll try to create such thing.

So you'd need to have the macro wait for .4 seconds to see if another insert press occurs, that makes sense. Yes that would work nicely.

This is perfect. Thank you!
