As title. In Animation Editor, what's an easy way to select all keyframes (from different channels) at crtain frame or frame range? For example, I'd like to select all keyframes at Frame 24:



I can drag a box like this. But it's error prone: if I didn't zoom out the view first, I might miss some keyframes whose values are very small or very large.

In dopesheet, there is an "All Displayed" row for this purpose:



But I don't know how to do this in graph view.

I don't think there's a way. Usually this operation means you're trying to do some retiming so I just shift+click on the player and move them instead of using the graph editor.
