[ka-Map-users] auto query

proceeding down the key-modifier path, it is possible to detect shift/
ctrl/alt keys when the mouse events happen, so a possibility is to
detect ctrl-click or ctrl-drag as query mode making it reasonably
seamless
On the same note, we could use shift-drag as a zoom box and right
click as zoom out.
What about:
| none | shift | ctrl | alt
----------------------+-----------+-----------+-------------+----------
left click | | zoom | query point |
----------------------+-----------+-----------+-------------+----------
left double click | recenter | | |
----------------------+-----------+-----------+-------------+----------
left click-and-drag | pan | zoom box | query rect |
----------------------+-----------+-----------+-------------+----------
right click | menu? | | |
----------------------+-----------+-----------+-------------+----------
right double click | | | |
----------------------+-----------+-----------+-------------+----------
right click-and-drag | | | |
----------------------+-----------+-----------+-------------+----------
The intention would be to have all this in kaNavigator so that
kaQuery would not be required, but possibly make the query actions
optional.
I think we should reserve the right click stuff for a possible
context menu.
Further discussion required :)
