Rotating camera view in Grease Pencil Draw Mode in Blender 2.8 I'm new Blender and I'm really excited about the Grease Pencil feature but I'm finding it difficult to achieve a function I use in other 2D animation programs, namely rotating/rolling the camera view while in a drawing mode.

In Toon Boom's products you have the ability to rotate the camera view of the canvas to make it easier to draw at an angle without transforming the drawn elements. To do this you simply hold Ctrl+Alt (which brings up a overlay of an animation disk) and then Left-Drag to set the rotation angle. To reset the view you press Shift+Z.



To rotate the camera view in Blender I find I must escape out of Draw Mode to Object Mode, select the camera, rotate/roll the view, and re-enter the Draw Mode.

In searching for a better solution I found this which links a video that supports a similar feature  but I feel it's inefficient.

The link goes on to explain that pressing R will achieve what I want but I don't seem to be able to get it to work as described.

I believe I should be able to write a script to add a shortcut. I spent some time on it but not being familiar with Blender scripting I find it difficult to even know how to approach this problem.

I found a simple framework here for adding a shortcut that seems to work but the business logic escapes me. Essentially my approach has been to assign a keyboard shortcut to Ctrl+Alt+Left-Drag while in Draw Mode to go directly into rotating/rolling the camera, and then upon release go back to Draw Mode on the object I was just drawing in.

Does anyone have similar script or helpful direction?
As others have already pointed out that Shift + Numpad 4 and Shift + Numpad 6 rotate the view by increments. This is ok and already works on the default set up.
For me, the better solution was to go to Edit &gt; Preferences Keymap under Grease Pencil &gt; Grease Pencil(global) press Add New. From here set your preferred key binding (I chose Middle Mouse Button ) then click the little &quot;expand&quot; arrow, add any modifiers (I chose Shift + Alt) and type `view3d.view_roll&quot; into the command box.
And that's it, this allows arbitrary rotation while holding Shift + Alt + Middle Mouse Button . To reset press Shift + Numpad 1.
