Canopy in 4.35 is not only spider. There is a canopy open close switch and once closed the spider to lock
For 2d and Alt Tab in 4.35 you can use Alt+Enter to switch 2d from windowed/borderless mode to fullscreen mode and then switch back to borderless before entering 3d to be able to stable Alt Tab. CTRL + Enter switches between windowed and borderless mode
Just thought I would point out that when writing a manual of any description it is good practice to have page 1 followed by page 2 etc. I know this was probably missed out by cutting and pasting pages from previous manuals and not being able to change the images. If you wish I could do you a new copy of this manual with the page numbers correctly in place and the sections corralated with the main Index. The offers there, just email me if you wish to have it done, or just leave it as it is.
Quite welcome. Buffering outside of the keyboard itself (within any of BMS/FAF or a scrip) is one more link it the chain - thanks to you for pointing that out.
