Is there any means to use the Ksnapshot with hot keys?? Something like Print screen and have a full picture of screen, Alt+PrintScreen and we have an area of the screen, Ctl+PrintScreen and we have a picture of the screen under the cursor.

+++++++++++

This situation was created because I need to take a picture of Kmix and it's 2 child windows (brought by right clicking on empty area of kmix). If I have these 3 windows of kmix and call ksnapshot, the 2 child windows go away.

You can set / look up the keys in the control center under "keyboard shortcuts" on the "general" tab (Note: Names translated from german). On my system I have:
Alt-Printscreen: Snapshot of single window
Ctrl-Printscreen: Snapshot of whole desktop

I'm not sure if ksnapshot must already be running in the background for this to be useful (you still have to give it a name and save it, I think)

But if I understand correctly what you're trying to do you could also use the snapshot delay that you can set in the ksnapshot dialog.
Set it to, say, 10 seconds, switch to kmix, produce the child windows and wait the rest of the time to pass...

I just tested it. Those shortcuts don't seem to use ksnapshot. They copy the screenshot into the clipboard. You can paste it from there.
I tried with kword and it worked. But better find an image manipulation program...

Now I need to taka a snapshot of the alsamixer screen. Which is in the console (ctl+alt+F2). I tried the same delay techinic but it did not work.

I don't know if that is possible at all. At least it's not so straighforward and nothing that can be configured in KDE. The X Window system (and KDE which runs on top of it) is not aware of what goes on on the consoles, AFAIK. If you hit Ctrl-Alt-F2 then X is still running but it is no longer in charge of your graphics card, mouse and keyboard. So you'd have to search for a way to create a screenshot elsewhere, not in X / KDE.

You could try to run alsamixer in KDE's "konsole" and take a screenshot of that window, though.

I could not find the shortcuts you mentioned. Probably they were not made yet. I'll try to have them done.

I don't remember if they were there by default or if I had set them myself in the KDE control center. The important thing is that the actions are there in the list...
