an easy question:
how do i make turrets on vehicles?

and:
can i change the anim an unit will stand when entering a transport vehicle?
(this "i grab the whatever is above me" anim)

and:
if i select an uv component and make the textureeditorwindow fullsize, the other component diaspear, till i select another model, how can i fix that?

[SOLVED]and:
why cant i set sometimes keyframes in xsi? (the button is grey)[/SOLVED]

[SOLVED]and:
in all pictures i see, there is a "tree" in the explorer, i cant get such a tree, if i drag an object under a null, the object stays still on its place and i cant see it under the null, but the null is the models parent.
if i cut a model and paste it into a null, the object is under the null and a "copy" of the object is still visible on the objects old place[/SOLVED]

[SOLVED]and:
undo and redo are disabled now X-([/SOLVED]
how can i fix that?

To answer your last question first:
Under File select Preferences, that will open another window in that find the heading General and click on it the level of undo is set at the top on the right side window.

For the greyed out anim key unless you have an object and one of the transitions selected it won't be selectable. You should always try to make sure all the X,Y & Z are selected use the button that looks like:

okay bad representation but I am sure you get the idea.

Post a picture of you XSI Explorer tree so can get a better idea of what you mean.

Putting a turret on a vehicle is fairly easy. The thing to remember is the turret parts can't be merged with the rest of the model they have to be separate. Also they have to have a proper parent child structure. Meaning the turret base would be parent the sideways rotation would be a child of that the up down part of the gun would be a child of that and the fire hardpoint would be a child of up down part. The other part is you have to have a .option file for the mesh, have a look at the ALL_hover_tank as an example. Takes a bit of playing to understand and get it right.

thank you for the help, but ive another problem:
xsi is not showing any property page now
if i click merge, xsi merges without asking me everything
how can i fiy that?
im extremely frustrated now

Don't copy the model. To make a new, complete fresh, finished mesh of more/an object(s) merge them as you always do, with UVs or not, if you want ( ), then press U, and press CTRL+A Use rightmouse button on the selected polys (red) and select Extract Polygons (delete) This so called "Polymesh_detached" is under scene-root, and individual/free of other crap, so you can do with it and place it where-ever you want

i dont mean that,
as example: minologuy has in his vehicletut an explorer-image with every bone, mesh,hp in a cool "three" hirarchie
i cant get such a hirarchie, i think theres somewhere an option disabled

File>Preferences>Interaction>Property Editors/Views tab and check the box beside Popup Property Editors on Node Creation

Press 6 on the keyboard to bring up a floating Layer Control window or click on the KP/L(Keying Panel/Layers) tab located beside the MCP tab at the lower right of the screen, but i'm not sure if that's what you mean.

thank you for your help,it was my fault, i openend the current layer not the sceneroot in the explorer
