Miscellaneous Blender VSE settings used for the recent project

Some settings and shortcuts I revised when working on a recent project - 

I thought that I should prevent the creation of "proxies" in Blender VSE (Video Sequence Editor) since the working SSD was only 256 GB, with only around 100 GB free. 

https://vse-docs.readthedocs.io/video_editing/setup/proxies.html

First, I set the 

Proxy setup to Manual

Proxy render size to 25%

Then I thought of disabling proxies altogether, so set the 'Use Proxies' checkbox to False (pull out menu on right of rendered view)

Image showing all these, from the page above,

How to rotate an HDRI background - https://www.youtube.com/watch?v=fqd4mc42sZQ

Shading tab - Choose World instead of Object as the subject of the shading editor, rotate using Vector Mapping node ahead of the single image HDRI as in the screenshot below,

Cutting video clips into pieces which do not show the previously existing clip sections when stretched - is by "Hold Split" - https://vse-docs.readthedocs.io/video_editing/edit/montage/transform.html#split
Shift + K to 'hold-split' at the cursor.

Shift + A is the shortcut key to add speed control strip (and many other things) - https://vse-docs.readthedocs.io/video_editing/edit/effects/speed.html - Add > Effect > Speed Control

Similarly, for a cross-fade transition, select begin clip, Shift click to select end clip, then Shift+A - Add > Transition > Cross - https://vse-docs.readthedocs.io/video_editing/edit/effects/transition.html - we can change the order of the transition later, if needed, from the side bar, by changing the Input 1 and Input 2 strips as in the screenshot below.
