What I really like about the editor is how the controls seem to aim at mimicking those of Blender, which is the obvious choice of modelling software for any Urho3D developer.
I understand it’s a work in progress, but here’s a list of things I ran into about the Blender controls in the Urho3D editor that were found not to be as in Blender (yet):
[spoiler]Ctrl+G should show a naming dialog and parent the selection to a new node with that name.
Numpad 4, 2, 6 and 8 should rotate the camera, Num[+] and num[-] and Ctrl+mmb should move forward and backward
Num[.] should center view on selection
Delete should also delete, not only X
Select/Deselect all should done with A instead of Ctrl+A
Shift+A should bring up the create menu under the cursor
P should pause/play the game
pop-up menus should appear under cursor and move the cursor out of them should close them
arrows should navigate pop-up menus
enter/return should confirm pop-up menus
Ctrl+N should load default scene instead Ctrl+Shift+N
G/R/S should activate the action instead of selecting it
(Shift+)X/Y/Z should lock the manipulation to an axis or plane
Escape should cancel the manipulation, lmb/Space/Enter should comfirm it
Ctrl+Space should hide the manipulator
Shift+D should initiante a grab operation on the duplicate
Fly mode:
Tab to enable/disable gravity
Teleporting using space or mmb
Escape/rmb should return to previous position
Shift/Alt/scroll speed up/down
lmb/enter should apply view change
3D cursor:
Missing yet which is an awesome Blender feature. In the Urho3D Editor it would be awesome for array-like placement of duplicate objects.
. , Ctr+. Ctrl+, for changing pivot mode
Shift+S for the snapping menu
Arithmatic should be allowed in number fields that are applied on enter.
Having an ‘active’ member of the selection is important for certain operations:
Enable/Disable Lock/Unlock Nodes and Components in the hiearchy as well[/spoiler]
Thought it might be a useful reference. It is very likely that this list is not complete (and outdated).
