Bug#739577: freeciv-client-gtk: unit/tile info tied to middle mouse button only

[pasky at ucw.cz]

Package: freeciv-client-gtk
Version: 2.4.2-1
Severity: minor

Dear Maintainer,

the unit/tile info (combat stats etc.) is tied just to the middle mouse
button.  However, e.g. the thinkpad notebooks can use the middle button
to emulate a scrollwheel if held, which is extremely useful but
interferes with this.  (Curiously - just tapping the middle mouse button
normally retains its function, e.g. pastes in a terminal, but has no
effect in the freeciv client.)

I suppose other users of funny input devices might be impaired by this
as well.  Overally, it would be nice if there was an alternative way to
trigger this functionality, perhaps ctrl + LMB or some such.  Some
googling suggests alt + LMB might trigger it on some platforms, but that
moves a window in X11 (and even in fullscreen mode, doesn't seem to have
any effect here).

Thanks for considering this!
