I remember with older version of Blender i could scrub through the timeline using alt + mouse scroll. In the last couple versions, not sure from which, this doesnt seem to work anymore.
Is it a certain setting? Ive checked key bindings/shortcuts and saw frame -1/+1 uses alt +mouse up and visa versa. But it doesnt work???
Sorry, ive should have posted some more info on this and my system. Im using mac with a mighty mouse, therefor i have emulate 3 button mouse. But i dont think its cause of that, in other versions i also had this mouse.
When i use factory settings it still doesnt seem to work??
