view all image?

[SurfingAlien]

first, sorry if it's been already discussed or suggested (I searched the forum with no luck).

I wonder if a "view all" button or shortcut (like ctrl+0 in Photoshop, to be clear) does make sense in the render viewport. I'm not talking of changing the camera point of view for the current rendering but just a (temporary) option to see all the image in the viewport even if we're rendering at, say, a double full screen res.
Working on a 1440x900 screen I sometimes get lost and have to choose the framing by "guesstimation"

thanks,

use ctrl - left click to pan the image.
use ctrl - mouse wheel to zoom/unzoom.

simple as that

thanks,
now I see what was the problem: in OSX ctrl+mouse wheel is locked to the screen magnifier... I had to disable it (no way I could change it to cmd+ or alt+ mouse wheel because I need them in other apps).

cheers,
A
