Myabe a silly ? Maybe not. Cycling units..

[Doctahg]

I would like to be able to just cycle through my units. Either I am missing a key command or it doesn't work. the peirod and the comma are supposed to do this I thought, but they do not cycle my units with or without any moves left for the units. Am I missing something? It's pretty annoying going thtough alot of units now as my game gets alot bigger. I am not seeing anything else on the key list.
Any help would be appreciated!

And using the arrow right and left on the unit screen doesnt work either!

there's an option in the interface option, tick it, you will be auto bring to next unit with moves
