I found Control-LeftMouse fairly quickly but I've a few other gripes about the Control Interface. Maybe if I share them, we can find solutions.

-- Dragging out using Control-LeftMouse doesn't always seem to work when the units are grouped, though ungrouping them (but leaving them selected obviously) does. There's a Control-L command which might be relevant but I'm not sure it is having any effect. The problem is they get redrawn all over the place, not in a line where you are dragging.

-- Dragging out as above doesn't work if the start or end of the drag is over a unit's current position. IMHO that shouldn't matter (either the unit is one of the ones that is being repositioned or I'm about to move it somewhere else).

-- Changing facing using to be so easy in M:TW. Now we have the , and . keys but I once found a group of units wandering randomly around instead of doing what I wanted. In any case, it isn't always easy to get the exact facing you want using these commands.

-- Moving a group in formation and getting them to resume their current facing when they arrive (Alt-LeftMouse in M:TW was it? - my fingers know but my brain isn't sure!). Can this oh so useful task be done in R:TW? All I've managed so far is move them then change their facing once they reach their new position, but this is a lot less efficient, both in time and clicks.

-- In M:TW, while you were dragging out a formation, you could use the RightMouse button to toggle the depth of every unit either relative to their original numbers or (the useful one) relative to the current unit numbers. So a unit down to 50% strength could be reformed with its appropriate depth (though with 1/2 the frontage obviously). Doesn't work in R:TW, can it be done some other way?

-- It would be nice if one of the preset formations (Shift 1-?) could get a Roman army to form up in pre-Marian manipular formation, though I can see this would be tough. While I'm mentioning the Shift-number preset formations: the only time I used one they formed up in 3 lines, missiles at the front as expected. I refined it a bit (Cavalry on flanks, archers behind infantry) then grouped the whole army and sent it marching. When it got to its destination it had reformed into the preset formation. Anyone else noticed that?

That's enough for now, though I'm sure there are others at the back of my mind somewhere. I must say the most recent mods and batles I've played have made me more optimistic about the full game: control of armies is still tough but I can see some decent enemy AI running the battles (sometimes).
And the killing speed isn't quite so bad once unit stats are more balanced. Speed still far too much though but anyway, this is all for another thread...
