[Gmsh] Zoom keyboard command?

[Richard Crozier]

Hello,

I'm a new gmsh/getdp user and have a query about zooming in the gmsh 
interactive GUI. Basically I would like to know if there is a keyboard 
shortcut to zoom in and out as I find the mouse actions a bit fiddly 
sometimes, especially when I'm trying to use a laptop trackpad!

If there is no shortcut for this, can I suggest one is introduced 
whenever the developers get a chance? I suggest the plus and minus keys 
for example, or perhaps shift and the arrow keys (although I would 
actually prefer it if you could pan and rotate with the arrow keys by 
holding shift and CTRL respectively).

Anyway, thanks for all your efforts, it seems like a really cool program 
from my initial attempts to use it!

Thanks,

Richard
