Hi I actually like pressing the space bar for navigation (Houdini style) instead of "alt" (Maya style) and then LMB, MMB and RMB for viewport navigation. I find that this is the most ergonomic way of working for me, but I can't seem to assign the space bar for as it adds it as a "tilda" with the mouse button and not as "plus".
Essentially what i want to do is:
Space+LMB
Space+MMB
Space+RMB
for navigation, is there a textfile one can't manipulate?
Another reason for space, is that I can easily reach other buttons for working I find the alt buttton Maya style navigation is too close to other functions/modifier buttons
