[scribus] tab-through selections

[Nik]

Hi All,

One problem that many GUI applications have is that of selecting smaller 
objects that are "under" larger ones. Scribus certainly has this issue 
with objects such as lines or frames of any type.

One way to select a smaller frame that is under a larger frame is to 
draw a selection box starting in the margin (and hence outside any 
frame) and encompassing the smaller frame.

However, this seems to be counter-intuitive to many people (some people 
I've taught this to repeatedly still fail to select such frames).

So, I would like to suggest an additional approach.

Enable a system similar to the Alt-Tab implemented by many windowing 
systems that lets the user cycle between a list of possibilities. There 
could be a few modes:

1. If no objects are selected on the current page, then cycle between 
all objects on the page
2. If the currently selected object covers other objects, cycle between 
all of those
3. If multiple objects are selected, cycle between all of those - and 
possibly any objects that they cover.

I am thinking that Alt-Click would be a reasonable gesture for this 
operation, but I seem to recall that some of the systems (Mac or 
Windows) only supports 2 qualifier keys for mouse clicks, so maybe we 
need something else, such as perhaps Ctrl-Tab?

Cheers!
