Check the documentation, I have reasons to believe function keys can be defined. 
You should be able to define <alt><tab> either in the menu or in a function-key.

The root of all evil is that the os at the desktop does not forward the 
<alt><tab> combination so the applications (here `vncviewer`) does not see it at 
all and hence cannot do anything about it.

VMWare has the same problem. They have re-assigned <ctrl><alt><del> to 
<ctrl><alt><ins> for example.

In the end, the best way is to have some customizable keys, like the 
function-keys, then users can define their own mapping for frequently used 
combinations. For the not so frequently used combinations, a virtual-keyboard 
does suit a need. If the local or remote machine is unix, the application 
`xkeycaps` can do that for all (and many more) keyboards you can imagine: it can 
redefine roughly all keys and it can suit as a virtual keyboard.
