How do you select all keyframes to the right or left in the Dope Sheet?

How do you select all keyframes to the right, or to the left of the cursor in the Dope Sheet?

I’m pretty sure I once found a way…

ALSO: How do you scale selected keyframes in the Dope Sheet, so the following unselected frames are dragged along (so they adjust to the time change)?

If you look there is a Select menu entry on the dopesheet header. It would be logical to look in there for select options. If you do look there you will see the [ and ] shortcuts

Proportional editing works the same in the dopesheet on keyframes as it does with vertices in the 3d viewport

OK, I agree - I should have looked there; that menu is an absolute gold mine.

Absolutely great, thank you!
