Shortcut for 2.5x speed

[abemail1]

Hi there,

on a mac, I can playback 2x speed by pressing L twice. If I then press Shift+L 5 times I can playback at 2.5x speed.

Is there anyway to create a shortcut to immediately playback at 2.5x?

I can't use 3x since at that speed I can't understand the audio.

TIA
