How to control camera effectively

[AndrewRed]

I'm struggling very much to use effectively use the camera.
I have played this game a lot years ago (some 20 I think, but I remember it was easier than now to move on the map)

I have a 4k screen.

I am a bit acquanted to use Google Earth and the fluidity of that!

In CM, black sea my worst problems are:

1) Sometimes I can't pan my camera back with the mouse, but it sticks on the "middle" of the map (or it seems over the unit currently selected).
But is simply refuses to go bak any further.
I can't imagine why.
(Also "S" control doesn't work)
I have to rotate 180° and go front...

2) I love to assign the quick numbers to my favourite units (CTRL+num). But two problems:
 2.a) When I reclaim them with ALT+num it doesn't simply select the unit (I often want to simply view where it is located on the map to have a reference, or see which enemies that unit have spotted), but the interface zooms on it. Is it possible to only select the unit?
2.b) The assigment only works during current battle, but when you reload a saved game you have to start again!

3) Can't have a whole vision of all the battlefield at once? (Also with number '9' it is not zoomed out enough)

4) CTRL+click on a spot on the map completely disrupt the zoom/view, etc... so that I dont' understand where I have ended up and is useless (I rember 20 years ago I used it A LOT)

5) I always want to: 
- quickly select (but first I have to find!) a unit of my interest
- Use TAB to center on it
- see what he can see from his perspective (so like number 1 or 2), but the problem with it is that it point the camera behind the unit, basically obstructing the view (so I have to pan front or use 'W')
How do you do this operation?

6) During battle I like to review it from different perspectives/units. I hear sounds of artillery or cannon, and I'd like to see where it happend. But how can I spot where the hit come from or who has been hit? (I don't want to zoom out and completely loose my hard found perspective)

Probably I have a lot of other question, but (ouch), also too much for now...

Thank you

You may have backed into the edge of the map.  It's sometimes hard to tell if at a higher level.

Yeah... I find the Cntrl-Click method to instantly get someplace on the map most of the time gets you some place you don't want to go.  

Re the TAB to  the view from a unit.  Not sure what is your issue here.  You know you can click "V" to instantly reverse the view direction 180 degrees?

Basically everything else one learns from experience...
