Allow double-clicking

[spinlokd]

I would like to map a button to perform double-click, however the following does not seem to have an effect:
action =
{
type: "Keypress";
keys: ["BTN_LEFT", "BTN_LEFT"];
};
I think it's because it tries to send the keys at the same time, rather than one after another.
It'd be nice if it was possible to be able to send a list of keys executed quickly one after another
