Hey gang, I just spent far too much time making this blender key chart:
Someone’s probably made one already but whatever, I couldn’t find it. So anyway, it’s got all the shortcuts for object mode (in pink) and edit mode (in blue). Anything not written in pink or blue applies to both.
The background colour under the text tells you what modifiers you have to hold down. Ctrl is orange, shift is blue, alt is black.
So, “Triangles to Quads” is in blue on black on the J key, so you go into edit mode and press alt+J. Easy!
The keys are accurate for the current SVN trunk, which may or may not be the same as the official 2.48 release (it won’t be much different, if at all).
Anyway, enjoy! SVG and Inkscape files if you’re interested:
Edit: oops, meant to post this to news & discussion. Guess it kinda fits here though anyway. Maybe.
