Seriously, this missing feature is SOOO bad that I consider it a MAJOR BUG.
Ctrl Shift is NOT an acceptable solution, because as you scroll a large vi, you often hit on some non "open space", and then the click selects and drags some random wires. NOT COOL!! It means you cant have confidence in this feature.
Fix it.
Another way to do it is make "scroll"/"pan" in the menus, so that we can assign a shortcut to toggle it.
I have switched to Windows7 and LabVIEW 2011. Since then, the sideward scroll function works with the sideward push function of the scroll wheel of my Logitech mouse RX1000. ...and I am happy .
Shift + Scroll for horizontal scroll would be really nice. This is standard e.g. in Gimp and Inkscape and many other programs I guess. No need for special mouses.
There appears not to be any new features in LV2013 with regard to the hirzontal scroll feture, but I have been adviced to use
ctrl+shift and having the auto-tool selected (green box in Tools) - and who has'nt that. This brings up the panning "hand" which is better than nothing.
But I still mis something which is "standard" in many other programs like the shift-scroll. Hmm, maybe 2014?
